The Quasar Feedback Survey: Ionised Outflows in type 2 QSOs with MUSE data
M. Bianchin, C. M. Harrison, T. Costa +13
We study ionised gas properties in a sample of 18 luminous (log L erg/s) obscured QSOs at 0.085<z<0.2 observed with VLT/MUSE as part of the multi-wavelength Quasa…
ALMA visits the QSO MUSEUM: Connecting molecular gas and the cool circumgalactic medium around 37 z~3 quasars
Jelena Ritter, Fabrizio Arrigoni Battaia, Bo Peng +7
Extended Ly emission is ubiquitous around quasars and traces the cool circumgalactic medium, providing insights into halo gas dynamics and active galactic nucleus feedback. Howe…
A 6.2 Quasar on the Local M- Relation Quenching Its Host Galaxy from the Aether Survey
Weizhe Liu, Emanuele Paolo Farina, Xiaohui Fan +19
We report JWST/NIRSpec integral field unit (IFU) observations of the quasar J15124422 at from the Aether survey. At 900 Myr after the Big Bang, this object al…
Stellar feedback SPICEs up [C II] emission in the first galaxies
Aniket Bhagwat, Tiago Costa, Benedetta Ciardi +1
The bright [C II] 158 micron line is widely used to trace star-forming gas and feedback-driven outflows in high-redshift galaxies. Using the SPICE simulations, we investigate how b…
Exploring the gaseous halos of z>3 radio galaxies with UVES and JWST/NIRSpec
Jelena Ritter, Wuji Wang, Dominika Wylezalek +3
High-redshift radio galaxies (HzRGs) are among the most massive galaxies in the Universe and sites of extreme active galactic nuclei (AGN) feedback processes, powering energetic ra…
Constraining the nature of active galactic nuclei through circumgalactic Lya emission at z=2-3
Shiwu Zhang, Zheng Cai, Fabrizio Arrigoni Battaia +8
We present a comprehensive analysis of circumgalactic Lya nebulae around 59 unobscured and 26 obscured quasars at z=2-3, observed with the Keck Cosmic Web Imager (KCWI), to constra…
