C. Cheng,P. N. Appleton,P. Duc,Yu Gao,Ning-Yu Tang,M. S. Yun,Y. S. Dai,J.-S. Huang,Ute Lisenfeld,Florent Renaud +9 more
TL;DR: In this article , the authors report atomic hydrogen (H i ) observations in the vicinity of the Stephan's Quintet (SQ) with a smoothed sensitivity of 1 σ = 4.2 × 10 16 cm −2 per channel (velocity bin-width Δ v = 20 km s −1 ; angular resolution = 4′), which are about two orders of magnitude deeper than previous observations.

TL;DR: Frye et al. as discussed by the authors reported spectra in the 950-1370 nm observer frame of two of the galaxy images obtained with Large Binocular Telescope (LBT) Utility Camera in the Infrared (LUCI) in long-slit mode two weeks after the JWST observations.

T Garratt,James E. Geach,Yoichi Tamura,Kristen Coppin,M. Franco,Yiping Ao,C.-C. Chen,C. Cheng,David L. Clements,Y. Dai,Helmut Dannerbauer,Thomas R. Greve,Bunyo Hatsukade,Ho Seong Hwang,L.

TL;DR: In this article , the authors presented the S2LXS XMM-LSS catalogue, which comprises 40 sources detected at>5 sigma significance, with deboosted flux densities in the range of 7mJy to 48 mJy, showing that the observed 850um number counts are best reproduced by model predictions that include either strong lensing or source blending from a 15 arcsec beam.
The Evolution of Brightest Cluster Galaxies in the Nearby Universe II: The star-formation activity and the Stellar Mass from Spectral Energy Distribution
G. Orellana-Gonz'alez,P. Cerulo,Giovanni Covone,C. Cheng,Roger Leiton,Ricardo Demarco,M. Gendron-Marsolais +6 more
TL;DR: In this article , the authors estimate stellar masses and star-formation rates (SFR) through SED fitting and study the evolution of the SFR with redshift as well as the effects of BCG stellar mass, cluster halo mass and cooling time on star formation.
