Optimal intrinsic alignment estimators in the presence of redshift-space distortions Open
We present estimators for quantifying intrinsic alignments in large spectroscopic surveys that efficiently capture line-of-sight (LOS) information while being relatively insensitive to redshift-space distortions (RSD). We demonstrate that …

JADES: carbon-enhanced, nitrogen-normal compact 980, 242galaxy at z = 11.2 Open
Over the past few years James Webb Space Telescope (JWST) has been a major workhorse in detecting and constraining the metal enrichment of the first galaxies in the early Universe and finding the source of the ionization of their interstel…

Clustering of DESI galaxies split by thermal Sunyaev-Zeldovich effect Open
The thermal Sunyaev-Zeldovich (tSZ) effect is associated with galaxy clusters - extremely large and dense structures tracing the dark matter with a higher bias than isolated galaxies. We propose to use the tSZ data to separate galaxies fro…
