Velocity reconstruction in the era of DESI and Rubin (part II): Realistic samples on the light cone
Boryana Hadzhiyska, Simone Ferraro, Bernardita Ried Guachalla +1
Reconstructing the galaxy peculiar velocity field from the distribution of large-scale structure plays an important role in cosmology. On one hand, it gives us an insight into stru…
Velocity reconstruction in the era of DESI and Rubin (part I): Exploring spectroscopic, photometric & hybrid samples
Bernardita Ried Guachalla, Emmanuel Schaan, Boryana Hadzhiyska +1
Peculiar velocities of galaxies and halos can be reconstructed from their spatial distribution alone. This technique is analogous to the baryon acoustic oscillations (BAO) reconstr…
class_sz I: Overview
B. Bolliet, A. Kusiak, F. McCarthy +16
class_sz is a versatile and robust code in C and Python that can compute theoretical predictions for a wide range of observables relevant to cross-survey science in the Stage IV er…
Cosmological shocks around galaxy clusters: A coherent investigation with DES, SPT & ACT
D. Anbajagane, C. Chang, E. J. Baxter +111
We search for signatures of cosmological shocks in gas pressure profiles of galaxy clusters using the cluster catalogs from three surveys: the Dark Energy Survey (DES) Year 3, the…
The Atacama Cosmology Telescope: High-resolution component-separated maps across one-third of the sky
William R. Coulton, Mathew S. Madhavacheril, Adriaan J. Duivenvoorden +151
Observations of the millimeter sky contain valuable information on a number of signals, including the blackbody cosmic microwave background (CMB), Galactic emissions, and the Compt…
The Early Data Release of the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +266
The Dark Energy Spectroscopic Instrument (DESI) completed its five-month Survey Validation in May 2021. Spectra of stellar and extragalactic targets from Survey Validation constitu…
