Euclid Quick Data Release (Q1). Exploring the complexity of quenching processes across time, environment, and mass through recently quenched galaxies

Euclid Collaboration, Z. Mao, L. Pozzetti +308

Recently quenched galaxies (RQGs) provide insights into galaxy quenching. We present a photometric and spectroscopic analysis of RQGs using the first Euclid Quick Data Release (Q1)…

Euclid: Disky titans - surprisingly high star formation activity and gas content in two brightest group galaxies at z~0.75

F. Gentile, E. Daddi, D. Elbaz +166

We present the discovery of two disky titans in the first data release of the Euclid satellite. These sources are massive (M>10^11 Msun) star-forming (SFR~20 Msun/yr) discs located…

LeMMINGs VII: 5 GHz, 50 mas e-MERLIN observations of a statistically complete sample of nearby AGN

D. R. A. Williams-Baldwin, R. D. Baldi, R. J. Beswick +36

We present 5 GHz e-MERLIN radio images at 50 mas resolution of the nuclear regions of the Legacy e-MERLIN Multi-band Imaging of Nearby Galaxies survey (LeMMINGs), the deepest stati…

The Carousel Lens I: A Spectroscopic Survey of the Carousel Lens Field

Jackson H. O'Donnell, Demetrius Y. Williams, Tesla E. Jeltema +18

We present a spectroscopic survey of field galaxies and lensed sources in the vicinity of the strong lensing galaxy cluster known as the Carousel lens at z=0.49. Using both Gemini/…

Euclid Quick Data Release (Q1). Quenching precedes bulge formation in dense environments but follows it in the field

Euclid Collaboration, F. Gentile, E. Daddi +321

(Abridged) The bimodality between star-forming discs and quiescent spheroids requires the existence of two main processes: the galaxy quenching and the morphological transformation…

RGC: a radio AGN classifier based on deep learning. I. A semi-supervised multiclass model for VLA images

M. S. Hossain, M. S. H. Shahal, K. M. B. Asad +10

Bent radio active galactic nuclei (RAGNs) -- wide-angle tails (WATs) and narrow-angle tails (NATs) -- trace dense environments in galaxy groups and clusters, yet no multiclass clas…

Time evolution of white-light flare accompanied by probable postflare loops on M-type dwarf EV Lacertae

Shinnosuke Ichihara, Daisaku Nogami, Kosuke Namekata +6

White-light flares are explosive phenomena accompanied by brightening of continuum from near-ultraviolet to optical, which occur on the Sun and stars. In order to investigate the m…

VLTI/GRAVITY enables the determination of the first dynamical masses of a classical Be + stripped and bloated pre-subdwarf binary

R. Klement, Th. Rivinius, D. Baade +7

HR~6819 is the first post-mass transfer binary system composed of a classical Be star and a bloated pre-subdwarf stripped star directly confirmed by interferometry. While the Be st…

astro-ph.SR2023

The CHARA Array interferometric program on the multiplicity of classical Be stars: new detections and orbits of stripped subdwarf companions

Robert Klement, Thomas Rivinius, Douglas R. Gies +8

Rapid rotation and nonradial pulsations enable Be stars to build decretion disks, where the characteristic line emission forms. A major but unconstrained fraction of Be stars owe t…

LeMMINGs IV: The X-ray properties of a statistically-complete sample of the nuclei in active and inactive galaxies from the Palomar sample

D. R. A. Williams, M. Pahari, R. D. Baldi +22

All 280 of the statistically-complete Palomar sample of nearby (<120 Mpc) galaxies dec > 20 degrees have been observed at 1.5 GHz as part of the LeMMINGs e-MERLIN legacy survey. He…

TOI-503: The first known brown dwarf-Am star binary from the TESS mission

Ján Šubjak, Rishikesh Sharma, Theron W. Carmichael +76

We report the discovery of an intermediate-mass transiting brown dwarf, TOI-503b, from the TESS mission. TOI-503b is the first brown dwarf discovered by TESS and orbits a metallic-…
