Exploring the interaction between the MW and LMC with a large sample of blue horizontal branch stars from the DESI survey

Amanda Byström, Sergey E. Koposov, Sophia Lilleengen +42

The Large Magellanic Cloud (LMC) is a Milky Way (MW) satellite that is massive enough to gravitationally attract the MW disc and inner halo, causing significant motion of the inner…

SpecDis: Value added distance catalogue for 4 million stars from DESI Year-1 data

Songting Li, Wenting Wang, Sergey E. Koposov +55

We present the SpecDis value added stellar distance catalog accompanying DESI DR1. SpecDis trains a feed-forward Neural Network (NN) with Gaia parallaxes and gets the distance esti…

Stellar reddening map from DESI imaging and spectroscopy

Rongpu Zhou, Julien Guy, Sergey E. Koposov +54

We present new Galactic dust reddening maps of the high Galactic latitude sky using DESI imaging and spectroscopy. We directly measure the reddening of 2.6 million stars by compari…

GD-1 Stellar Stream and Cocoon in the DESI Early Data Release

Monica Valluri, Parker Fagrelius, Sergey. E. Koposov +49

We present 115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence…

DESI Early Data Release Milky Way Survey Value-Added Catalogue

Sergey E. Koposov, C. Allende-Prieto, A. P. Cooper +40

We present the stellar value-added catalogue based on the Dark Energy Spectroscopic Instrument (DESI) Early Data Release. The catalogue contains radial velocity and stellar paramet…
