An extremely metal-poor Lyman emitter candidate at revealed through absorption spectroscopy
Dominika Ďurovčíková, Anna-Christina Eilers, Robert A. Simcoe +10
We report the discovery of a Lyman emitter (LAE) candidate in the immediate foreground of the quasar PSO J158-14 at at a projected distance $\sim29\ {\rm p…
Quasar lifetime measurements from extended Ly nebulae at
Dominika Ďurovčíková, Anna-Christina Eilers, Romain A. Meyer +7
The existence of billion-solar-mass black holes hosted in luminous quasars within the first gigayear of cosmic history poses a challenge to our understanding of supermassive black…
Kiloparsec-Scale Alignment of a Radio Jet with Cool Gas and Dust in a z~6 Quasar
Fabian Walter, Eduardo Banados, Chris Carilli +11
We present high-angular resolution (0.068", ~400pc) ALMA imaging of the [CII] line and dust continuum emission of PSO J352.4034-15.3373, a radio-loud quasar at z=5.83. The observat…
An Early Look at the Performance of IGRINS-2 at Gemini-North with Application to the ultrahot Jupiter, WASP-33 b
Yeon-Ho Choi, Ueejeong Jeong, Jae-Joon Lee +56
Ground-based high-resolution spectroscopy enables precise molecular detections and velocity-resolved atmospheric dynamics, offering a distinct advantage over low-resolution methods…
Disturbed cold gas in galaxy and structure formation
Siwei Zou, Robert A. Simcoe, Patrick Petitjean +18
Cold and cool gas (T K) in the circumgalactic medium (CGM) and its interaction with galaxies remain poorly understood. Simulations predict that cold gas flows into gala…
Another piece to the puzzle: radio detection of a JWST detected AGN candidate
Anniek J. Gloudemans, Kenneth J. Duncan, Anna-Christina Eilers +5
Radio observations can provide crucial insight into the nature of a new abundant and mysterious population of dust-reddened active galactic nuclei (AGN) candidates discovered by th…
