The DESI Survey Validation: Results from Visual Inspection of Bright Galaxies, Luminous Red Galaxies, and Emission Line Galaxies
Ting-Wen Lan, R. Tojeiro, E. Armengaud +79
The Dark Energy Spectroscopic Instrument (DESI) Survey has obtained a set of spectroscopic measurements of galaxies to validate the final survey design and target selections. To as…
Overview of the Instrumentation for the Dark Energy Spectroscopic Instrument
B. Abareshi, J. Aguilar, S. Ahlen +264
The Dark Energy Spectroscopic Instrument (DESI) has embarked on an ambitious five-year survey to explore the nature of dark energy with spectroscopy of 40 million galaxies and quas…
Modelling the galaxy-halo connection with semi-recurrent neural networks
Harry George Chittenden, Rita Tojeiro
We present an artificial neural network design in which past and present-day properties of dark matter halos and their local environment are used to predict time-resolved star form…
The DESI PRObabilistic Value-Added Bright Galaxy Survey (PROVABGS) Mock Challenge
ChangHoon Hahn, K. J. Kwon, Rita Tojeiro +16
The PRObabilistic Value-Added Bright Galaxy Survey (PROVABGS) catalog will provide measurements of galaxy properties, such as stellar mass (), star formation rate (…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
The role of the cosmic web in the scatter of the galaxy stellar mass - gas metallicity relation
Callum T. Donnan, Rita Tojeiro, Katarina Kraljic
Understanding the relationship between the cosmic web and the gas content of galaxies is a key step towards understanding galaxy evolution. However, the impact of the cosmic web on…
