This international conference is part of a series of conferences that have been dedicated to the topic of Cosmic Flows over the last two decades: most recently 2012 in Queensland, Australia, 2013 in Marseille, France and 2016 in Quy Nhon, Vietnam.
Progress has been made on various fronts — such as on the reconstruction and presentation of flow fields from peculiar velocity catalogues and surveys like 2MTF and 6dFGRS, first results from the SKA Pathfinders and the TAIPAN survey, and the 3D-visualisation front where sophisticated tools are now being used to scientifically analyse data sets such as HI-data cubes, cosmological maps, simulations, by immersing yourself inside the data using Virtual Reality to interactively view and interrogate the data using varying parameter settings.
Our aims are to discuss and review the following topics, with a vision to future goals:
- Distance determinations, redshift and peculiar velocity surveys
- Large-scale structures in the nearby Universe
- Surveys of the Zone of Avoidance
- Local voids and superclusters
- First results from new surveys (SKA Pathfinders, TAIPAN, etc.)
- Peculiar velocity surveys and catalogues (FP, TF, SNe, kSZ, CosmicFlows, etc.)
- Redshift space distortions in BAO Surveys (WiggleZ, BOSS, eBOSS, DESI, TAIPAN, Euclid, etc.)
- Distance ladder and H0
- Promising future methods: transverse velocities (GAIA, LSST, etc.)
- Cosmic flow fields
- Linear and non-linear velocity field reconstructions
- Comparison of redshift data and flow fields
- Bulk flows and velocity field models
- Visualisation and Modelling (to take place at the Iziko Planetarium and Digital Dome in Cape Town)
- New immersive tools and software of 3D-visualisation
- New approaches to modelling and fitting the peculiar velocity field
- Natural and efficient multi-dimensional inspection using Virtual Reality
The conference will consist of plenary sessions, with in-depth review talks and contributed talks on specific specialised topics, as well as posters, including selected panel discussions.

Venue & Accommodation
2020 will see the bicentenary of the establishment, in 1820, of of the The Royal Observatory at the Cape of Good Hope the precursor to the South African Astronomical Observatory (SAAO). This was the first permanent astronomical observatory in the southern hemisphere. Various events will be held throughout the year to mark this, with the highlight being a large international conference and astronomy festival in October 2020.
Moreover, the UCT Astronomy Department will be celebrating its 50th anniversary in this same year. Various research aspects in which the department has been active over the last 50 years will be highlighted in 2020 with special events and workshops. Given the long tradition over the existence of the UCT Astronomy Department in mapping the large-scale structure of galaxies and associated flow fields, we are particularly delighted to host the next conference in the series on ‘Cosmic Flows’ in the Western Cape.
STIAS (The Stellenbosch Institute for Advanced Study), Stellenbosch, South Africa
The conference will be held at STIAS, the Wallenberg Centre of the Stellenbosch Institute for Advanced Studies, about 30 min drive from Cape Town International airport (CPT), and about 40 min drive from Cape Town.
Stellebosch is picturesque with many cosy restaurants, guest houses and hotels. It is quite popular with tourists and entirely safe to wander around until late in the summer evenings. The town’s oak-shaded streets are lined with cafés, boutiques and art galleries. Cape Dutch architecture gives a sense of South Africa’s Dutch colonial history, as do the Village Museum’s period houses and gardens.Stellenbosch is located in South Africa’s Western Cape province, It is surrounded by the vineyards of the Cape Winelands and the mountainous nature reserves of Jonkershoek and Simonsberg.
How to get there from the airport
We recommend booking your shuttle with Ross Pinto <firstname.lastname@example.org>. A single trip between the airport and Stellenbosch will cost R600.
Uber is popular in Cape Town and the cost will probably be slightly less.
Some of the accommodations offer airport shuttle services.
You can also catch a taxi from the airport, but in that case we recommend going to the official taxi counter at arrivals, rather than one of the touts.
Because Stellenbosch such a popular tourist destination,we recommend you book your accommodation early.

We have selected two programmes for partners: a full-day excursion on Tuesday, February 19 and a three-hour excursion on Wednesday morning, February 20 while the conference delegates are at the Cape Town Planetarium for scientific talks. The programme highlights community experiences that are off the beaten track and highly recommended. You will be accompanied by certified tour guides and Peter Kraan, husband of Renee Kraan-Korteweg, will join on both tours. Please sign up with Peter as early as possible, latest by Monday, February 18 by sending an email to email@example.com. Please direct any queries about these excursions or any other sightseeing questions to Peter as well.
Tuesday, February 18: Khayelitsha Experience
This will be a memorable experience and a way to meet the locals and learn about their culture in a responsible and sustainable way. We head from Stellenbosch to Khayelitsha, the largest township in the Western Cape and the second largest (and fastest-growing) in South Africa. It is almost exclusively inhabited by people of the Xhosa tribe. Our first stop is at Siki’s Kofee Kafe, one of the first coffee shops in the “hood” and test his own blend while listening to his story. Afterwards, we enjoy a walk and learn about local culture, creative projects and meet local entrepreneurs like the Spinach King. We have the opportunity to leave an impact in the community by either painting an inspirational mural or creating a home garden. At lunchtime, we enjoy a traditional meal with a family and share our stories. After lunch, we see a local cultural choir dance group perform and join in if we wish.
The tour costs R1650 pp payable before the tour and includes shuttle to/from Khayelitsha, coffee, lunch, water, entrance fees at the cultural project, gardening and painting materials.
Pick-up at STIAS at 9 am, drop-off at STIAS at about 4 pm.
Wednesday, February 19: Cape Town City Centre
District Six, Company Gardens, Woodstock, Bo Kaap)
This morning we take you through some historical and cultural communities of the Cape Town City Centre. Starting at the Planetarium, we first stop at District Six Museum where you will meet locals that share their story of the forcible removals during Apartheid and see the visual images of that time. We drive into the area, still empty, where the removals took place. After that, we head to nearby Woodstock which has become one of the creative hubs of Cape Town and experience how gentrification is affecting the community while enjoying good coffee from Rosetta Roastery. We take a walk through the area and admire the street art. We then take a short drive into Bo Kaap and learn about the Cape Malay history and their colourful houses. After Bo Kaap, we enjoy a beautiful walk through the Company Gardens, one of the first VOC gardens to produce fruits and vegetables to supply the ships rounding the Cape. Today it is a public space where locals go to enjoy the beauty of the garden, the adjoining museums and a good place for photography. The walk ends at the Planetarium in time for lunch and the conference excursion after lunch.
The cost of the tour is R700 pp payable before the tour and it includes shuttle plus entrance fees at District Six Museum.
Pick-up at the Planetarium at 9 am, drop-off at the Planetarium at about 12.
Safety and other practical matters
Safety is our first concern and we advise you to use the same common-sense that you would in any other areas of the world. Avoid flashy jewellery and watches. Bring some cash for small gifts and souvenirs and feel free to take a camera. Locals rarely mind being photographed but if in doubt, ask. Comfortable walking shoes are a must, as well as sunscreen and a hat. For any questions and concerns, email Peter at firstname.lastname@example.org.
Sutherland trip 22/23 Feb
A visit to the telescopes at Sutherland on the weekend after the workshop has been arranged. Those who have signed-up will have received further information. If you are still keen to join the excursion, please urgently send an email to Ms Roslyn Daniels (ast.uct.ac.za).
The costs are approximately R2000.– per person including overnight accommodation in the Sutherland hotel and dinner in the town. Transport will be by minibus or bus and will take about 5.5 hours (it is a beautiful scenic trip on excellent roads). On the way to Sutherland a stop is planned in the picturesque, historic little place of Matjiesfontein where you can walk around, visit to the museum and get lunch (at your own expense). There will be a daytime tour of SALT (which is scheduled to be on engineering stand-down at the time) and a visit to the Las Cumbres Observatory, MeerLICHT and other small telescopes on the plateau. Return to Cape Town will be to arrive at approximately 17:00 on the Sunday, On the return trip, a stop can be arranged at the small but lovely Karoo Desert National Botanical Garden, which also offers lunch option (at own cost).
Depending on the requirements of the party it may be possible to drop some people at the airport.
