Combined tracer analysis for DESI 2024 BAO

D. Valcin, M. Rashkovetskyi, Hee‐Jong Seo, Florian Beutler et autres

Abstract This paper demonstrates how the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) and future baryon acoustic oscillations (BAO) analyses can optimally combine overlapping tracers (galaxies of distinct types) in the same redshift range. We make a unified catalog of …

Clustering analysis of medium-band selected high-redshift galaxies

Haruki Ebina, Martin White, Anand Raichoor, Arjun Dey et autres

Abstract Next-generation large-scale structure spectroscopic surveys will probe cosmology at high redshifts (2.3 < z < 3.5), relying on abundant galaxy tracers such as Lyα emitters (LAEs) and Lyman break galaxies (LBGs). Medium-band photometry has emerged as a potential technique for efficiently …

DESI Strong Lens Foundry II: DESI Spectroscopy for Strong Lens Candidates

Xiaosheng Huang, Jose Carlos Inchausti, C. Storfer, S. Tabares-Tarquinio et autres

We present the Dark Energy Spectroscopic Instrument (DESI) Strong Lensing Secondary Target Program. This is a spectroscopic follow-up program for strong gravitational lens candidates found in the DESI Legacy Imaging Surveys footprint. Spectroscopic redshifts for the lenses and lensed source are crucial …

DESI DR1 Ly$α$ forest: 3D full-shape analysis and cosmological constraints

Andrei Cuceu, H. K. Herrera-Alcantar, C. Gordon, C. Ramírez-Pérez et autres

We perform an analysis of the full shapes of Lyman-$α$ (Ly$α$) forest correlation functions measured from the first data release (DR1) of the Dark Energy Spectroscopic Instrument (DESI). Our analysis focuses on measuring the Alcock-Paczynski (AP) effect and the cosmic growth rate …

DESI DR2 reference mocks: clustering results from Uchuu-BGS and LRG

Elena Fernández‐García, Francisco Prada, A. G. Smith, Joseph DeRose et autres

The aim of this work is to construct mock galaxy catalogues that accurately reproduce the redshift evolution of galaxy number density, clustering statistics, and baryonic properties, such as stellar mass for luminous red galaxies (LRGs) and absolute magnitude in the $r$-band for …

Evaluating a whole-school approach to addressing gender-based violence in Scottish secondary schools (Equally Safe at School): a study protocol for a type I hybrid effectiveness-implementation trial

Claire Hamilton, Ruth Lewis, Carolyn Blake, Anthony Purvis et autres

INTRODUCTION: Equally Safe at School (ESAS) is a whole-school intervention to reduce gender-based violence (GBV) in secondary school. ESAS comprises self-assessment, student-led action group, two-tier staff training, curriculum enhancement and policy review. Schools set up key activities in Year 1 and embed …

Tripling the Census of Dwarf AGN Candidates Using DESI Early Data

Ragadeepika Pucha, S. Juneau, Arjun Dey, M. Siudek et autres

Using early data from the Dark Energy Spectroscopic Instrument (DESI) survey, we search for AGN signatures in 410,757 line-emitting galaxies. By employing the BPT emission-line ratio diagnostic diagram, we identify AGN in 75,928/296,261 ($\approx$25.6%) high-mass ($\log (M_{\star}/\rm M_{\odot}) >$ 9.5) and 2,444/114,496 …

Prevention of, and response to, sexual harassment at secondary school: A system map

Carolyn Blake, Ruth Lewis, Julie Riddell, Malachi Willis et autres

BACKGROUND: Sexual harassment in secondary school is common but only recently acknowledged as a widespread problem in the United Kingdom. There is limited research on how schools respond to incidents of sexual harassment. The aim of this study was to understand how …
