Overdensity of Lyman-Break Galaxy Candidates Around Hot Dust-Obscured Galaxies
Dejene Zewdie, Roberto J. Assef, Trystan Lambert +15
Hot dust-obscured galaxies (Hot DOGs), are a family of hyper-luminous, heavily obscured quasars. A number of studies have shown that these objects reside in significantly overdense…
The host galaxies of radio-loud quasars at z>5 with ALMA
C. Mazzucchelli, R. Decarli, S. Belladitta +13
The interaction between radio-jets and quasar host galaxies plays a paramount role in quasar/galaxy co-evolution. However, very little has been known so far about this interaction…
A Quasar-Anchored Protocluster at z=6.6 in the ASPIRE Survey: II. An Environmental Analysis of Galaxy Properties in an Overdense Structure
Jaclyn B. Champagne, Feige Wang, Jinyi Yang +21
We present paper II comprising a 35 arcmin \textit{JWST}/NIRCam imaging and wide-field slitless spectroscopy mosaic centered on J03053150, a luminous quasar at . The…
A Quasar-Anchored Protocluster at z=6.6 in the ASPIRE Survey: I. Properties of [OIII] Emitters in a 10 Mpc Overdensity Structure
Jaclyn B. Champagne, Feige Wang, Haowen Zhang +25
ASPIRE (A SPectroscopic survey of bIased halos in the Reionization Era) is a quasar legacy survey primarily using \textit{JWST} to target a sample of 25 quasars with NIRCam s…
No Redshift Evolution in the Fe II/Mg II Flux Ratios of Quasars across Cosmic Time
Danyang Jiang, Masafusa Onoue, Linhua Jiang +13
The Fe II/Mg II emission line flux ratio in quasar spectra serves as a proxy for the relative Fe to alpha-element abundances in the broad line regions of quasars. Due to the expect…
Far-Infrared and [CII] observations of a z=7 blazar
Eduardo Banados, Yana Khusanova, Roberto Decarli +7
We present millimeter observations of the host galaxy of the most distant blazar known, VLASSJ041009.05-013919.88 (hereafter J0410-0139) at z=7, using ALMA and NOEMA observations.…
