Field-level inference of growth rate from DESI BGS galaxy and ZTF supernova simulations

Corentin Ravoux, Bastien Carreres, Julian Bautista +60

Galaxy peculiar velocities are a powerful probe of the growth rate of structure at low redshifts (), measured through the combination . These constraints are imp…

Model-Independent Measurement of Baryon Gas Fractions through Galaxy-Galaxy Lensing and the Kinematic Sunyaev-Zel'dovich Effect

R. Henry Liu, Uroš Seljak, Simone Ferraro +52

Baryon feedback is a leading source of systematic uncertainty for cosmology from weak lensing, but measurements of the gas distribution around galaxies have largely relied on param…

A Unified Tracer Analysis of DESI DR2 Baryon Acoustic Oscillations

N. Sanders, H. Seo, M. Rashkovetskyi +65

We improve upon previous efforts to optimally combine overlapping galaxy samples in the DESI baryon acoustic oscillation analysis. By weighting each galaxy by its linear bias, over…

Improved constraints on the Milky Way potential using the M68 stream and DESI spectroscopic data

Carles G. Palau, Wenting Wang, Jiaxin Han +41

We present a selection of stars belonging to the stellar stream of the M68 (NGC 4590) globular cluster, also known as Fjörm. This star selection is an improvement on previous ones…

A Hybrid R-Theta Fiber Positioning Robot Using a Piezoelectric Bender for Radial Motion

Michael Schubnell, Tim Fanning, Andrew Hope +3

Future massively multiplexed spectroscopic surveys require focal planes with increasingly dense arrays of robotic fiber positioners. The DESI (Dark Energy Spectroscopic Instrument)…

Luminosity function of quasars at from SDSS and DESI

Gaocheng Yin, Linhua Jiang, Zhiwei Pan +54

We present a study of the evolution of type 1 quasars at , covering the peak epoch of quasar activity. The quasar evolution has been extensively explored by a variety of…
