Emission Line Predictions for Mock Galaxy Catalogues: a New Differentiable and Empirical Mapping from DESI
Ashod Khederlarian, Jeffrey A. Newman, Brett H. Andrews +43
We present a simple, differentiable method for predicting emission line strengths from rest-frame optical continua using an empirically-determined mapping. Extensive work has been…
Measuring the conditional luminosity and stellar mass functions of galaxies by combining the DESI LS DR9, SV3 and Y1 data
Yirong Wang, Xiaohu Yang, Yizhou Gu +42
In this investigation, we leverage the combination of Dark Energy Spectroscopic Instrument Legacy imaging Surveys Data Release 9 (DESI LS DR9), Survey Validation 3 (SV3), and Year…
Outlier Detection in the DESI Bright Galaxy Survey
Yan Liang, Peter Melchior, ChangHoon Hahn +3
We present an unsupervised search for outliers in the Bright Galaxy Survey (BGS) dataset from the DESI Early Data Release. This analysis utilizes an autoencoder to compress galaxy…
A Hierarchy of Normalizing Flows for Modelling the Galaxy-Halo Relationship
Christopher C. Lovell, Sultan Hassan, Daniel Anglés-Alcázar +8
Using a large sample of galaxies taken from the Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) project, a suite of hydrodynamic simulations varying both cosm…
PROVABGS: The Probabilistic Stellar Mass Function of the BGS One-Percent Survey
ChangHoon Hahn, Jessica Nicole Aguilar, Shadab Alam +33
We present the probabilistic stellar mass function (pSMF) of galaxies in the DESI Bright Galaxy Survey (BGS), observed during the One-Percent Survey. The One-Percent Survey was one…
Preliminary Target Selection for the DESI Bright Galaxy Survey (BGS)
Omar Ruiz-Macias, Pauline Zarrouk, Shaun Cole +28
The Dark Energy Spectroscopic Instrument (DESI) will execute a nearly magnitude-limited survey of low redshift galaxies (, median ). Clustering…
