Unveiling Hidden Lyman Alpha Emitters in the DESI DR1 Data
A CNN-based method automatically detects 19,685 hidden Lyman Alpha Emitters in DESI DR1 data with high purity and completeness.
Euclid: Asteroid rotation periods from the Euclid Ecliptic Survey
Researchers used Euclid data to determine spin periods for 889 asteroids, including 16 super-fast rotators, with 93% being first-time measurements.
Euclid Quick Data Release (Q1). AstroVink: A vision transformer approach to find strong gravitational lens systems
AstroVink, a vision transformer, efficiently identifies strong gravitational lens candidates in Euclid data, significantly reducing manual inspection.
Precision Kinematic Sunyaev--Zel'dovich Measurements Across Halo Mass and Redshift with DESI DR2 and ACT DR6: Part II. Bright Galaxy Survey and Emission-Line Galaxies
This paper presents the most significant kSZ detections to date for BGS and ELG galaxies, revealing insights into circumgalactic gas and feedback mechanisms.
Precision Kinematic Sunyaev--Zel'dovich Measurements Across Halo Mass and Redshift with DESI DR2 and ACT DR6: Part I. Luminous Red Galaxies
Using DESI and ACT data, this study precisely measures the kSZ effect around LRGs, revealing gas redistribution and stronger baryonic feedback.
Euclid: Scaled-up little red dots and other sources with v-shaped spectral energy distributions at z>4
Euclid observations identified 16 massive, high-redshift Little Red/Blue Dot candidates, significantly larger than those found by JWST.
