DESI Mg II Absorbers: Extinction Characteristics & Quasar Redshift Accuracy
Lucas Napolitano, Adam D. Myers, Vicky Fawcett +32
In this paper, we study how absorption-line systems affect the spectra and redshifts of quasars (QSOs), using catalogs of Mg II absorbers from the early data release (EDR) and firs…
Constraining the phase shift of relativistic species in DESI BAOs
Abbé M. Whitford, Hugo Rivera-Morales, Cullan Howlett +36
In the early Universe, neutrinos decouple quickly from the primordial plasma and propagate without further interactions. The impact of free-streaming neutrinos is to create a tempo…
The first identification of Lyman Changing-look Quasars at high-redshift in DESI
Wei-Jian Guo, Zhiwei Pan, Małgorzata Siudek +38
We present two cases of Ly changing-look (CL) quasars (J1306 and J1512) along with two additional candidates (J1511 and J1602), all discovered serendipitously at through…
The Atacama Cosmology Telescope DR6 and DESI: Structure growth measurements from the cross-correlation of DESI Legacy Imaging galaxies and CMB lensing from ACT DR6 and Planck PR4
Frank J. Qu, Qianjun Hang, Gerrit Farren +51
We measure the growth of cosmic density fluctuations on large scales and across the redshift range through the cross-correlation of the ACT DR6 CMB lensing map and gala…
Exploring the interaction between the MW and LMC with a large sample of blue horizontal branch stars from the DESI survey
Amanda Byström, Sergey E. Koposov, Sophia Lilleengen +42
The Large Magellanic Cloud (LMC) is a Milky Way (MW) satellite that is massive enough to gravitationally attract the MW disc and inner halo, causing significant motion of the inner…
Selection of high-redshift Lyman-Break Galaxies from broadband and wide photometric surveys
C. Payerne, W. d'Assignies Doumerg, C. Yèche +44
In this paper, we investigate the possibility of selecting high-redshift Lyman-Break Galaxies (LBG) using current and future broadband wide photometric surveys, such as UNIONS or t…
