The radiation from stars and active galactic nuclei (AGNs) creates photodissociation regions
(PDRs) and X-ray-dominated regions (XDRs), where the chemistry or heating is dominated …

The merger of two or more galaxies can enhance the inflow of material from galactic scales
into the close environments of active galactic nuclei (AGNs), obscuring and feeding the …

Virial black hole (BH) mass (M BH) determination directly involves knowing the broad-line
region (BLR) clouds' velocity distribution, their distance from the central supermassive BH (R …

We present an ACA search for [C i] 1–0 emission at 492 GHz toward large T Tauri disks (gas
radii≳ 200 au) in the∼ 1–3 Myr-old Lupus star-forming region. Combined with Atacama …

Recent work has revealed that the light curves of hydrogen-poor (Type I) superluminous
supernovae (SLSNe), thought to be powered by magnetar central engines, do not always …

We present results from the James Webb Space Telescope Director's Discretionary Time
Early Release Science program 1328 targeting the nearby, luminous infrared galaxy, VV …

Context. Emission lines that are indicative of active accretion have been observed for a
number of low-mass companions (M< 30 M Jup) to stars. Line variability is ubiquitous on …

The relationship between galaxy characteristics and the reionization of the universe remains
elusive, mainly due to the observational difficulty in accessing the Lyman continuum (LyC) at …

We present the first systematic study of 50 low-redshift (0.66< z< 1.63) iron low-ionization
broad absorption-line quasars (FeLoBALQs) using SimBAL, which represents a more than …

Ionized gas kinematics provide crucial evidence of the impact that active galactic nuclei
(AGNs) have in regulating star formation in their host galaxies. Although the presence of …
