Constraining the density distribution of the cold Circumgalactic Medium of quasars at z>2 through Lya, HeII and Ha emission
Andrea Travascio, Sebastiano Cantalupo, Titouan Lazeyras +16
Extended Lya emission is routinely detected around high-redshift quasars, revealing large reservoirs of cool circumgalactic medium (CGM). Its resonant nature complicates interpreta…
Enhancing WISE Infrared Imaging to Spitzer Resolution Using Deep Learning Super-Resolution
Saeed Rezaee, Shoubaneh Hemmati, Bahram Mobasher +5
We present a deep-learning framework that performs 4.6x spatial super-resolution from WISE W1 (3.4 micron) toward Spitzer IRAC Ch1 (3.6 micron), and characterize its behavior on th…
Little red dot variability over a century reveals black hole envelope via a giant Einstein cross
Zijian Zhang, Mingyu Li, Masamune Oguri +79
"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…
Ly Halo Properties and Dust in the Circumgalactic Medium of Star-forming Galaxies
Zhiyuan Song, Naveen A. Reddy, Yuguang Chen +7
We present Keck Cosmic Web Imager IFU observations around extended Ly halos of 27 typical star-forming galaxies with redshifts drawn from the MOSFIRE Deep Evolut…
Lyα profile shape as an escape-fraction diagnostic at high redshift
Anthony J. Pahl, Alice E. Shapley, Charles C. Steidel +3
While the shape of the Ly profile is viewed as one of the best tracers of ionizing-photon escape fraction () within low redshift (z~0.3) surveys of the Lyman continuum,…
A blind CO detection of a Distant Red Galaxy in the HS1700+64 proto-cluster
S. C. Chapman, F. Bertoldi, Ian Smail +7
We report the blind detection of 12CO emission from a Distant Red Galaxy, HS1700.DRG55. We have used the IRAM PdBI-WIDEX, with its 3.6GHz of instantaneous dual-polarization bandwid…
