Charting the Galactic acceleration field I. A search for stellar streams with Gaia DR2 and EDR3 with follow-up from ESPaDOnS and UVES

Rodrigo Ibata, Khyati Malhan, Nicolas Martin +10

We present maps of the stellar streams detected in the Gaia Data Release 2 (DR2) and Early Data Release 3 (EDR3) catalogs using the STREAMFINDER algorithm. We also report the spect…

Runaway stars masquerading as star formation in galactic outskirts

Eric P. Andersson, Florent Renaud, Oscar Agertz

In the outskirts of nearby spiral galaxies, star formation is observed in extremely low gas surface densities. Star formation in these regions, where the interstellar medium is dom…

Local starburst conditions and formation of GRB 980425 / SN 1998bw within a collisional ring

M. Arabsalmani, F. Renaud, S. Roychowdhury +9

We present the first spatially resolved study of molecular gas in the vicinity of a Gamma Ray Burst, using CO(2-1) emission line observations with the Atacama Large Millimetre Arra…

VINTERGATAN I: The origins of chemically, kinematically and structurally distinct discs in a simulated Milky Way-mass galaxy

Oscar Agertz, Florent Renaud, Sofia Feltzing +6

Spectroscopic surveys of the Milky Way's stars have revealed spatial, chemical and kinematical structures that encode its history. In this work, we study their origins using a cosm…

From lenticulars to blue compact dwarfs: the stellar mass fraction is regulated by disc gravitational instability

Alessandro B. Romeo, Oscar Agertz, Florent Renaud

The stellar-to-halo mass relation (SHMR) is not only one of the main sources of information we have on the connection between galaxies and their dark matter haloes, but also an imp…

VINTERGATAN III: how to reset the metallicity of the Milky Way

Florent Renaud, Oscar Agertz, Eric P. Andersson +5

Using the cosmological zoom simulation VINTERGATAN, we present a new scenario for the onset of star formation at the metal-poor end of the low-[/Fe] sequence in a Milky Way-like…
