A first look at quasar-galaxy clustering at
Jan-Torge Schindler, Joseph F. Hennawi, Frederick B. Davies +8
We present JWST observations of the environments surrounding two high-redshift quasars, J02520503 at and J10072115 at , which enable the first constraints…
A Little Red Dot at within a Large Galaxy Overdensity
Jan-Torge Schindler, Joseph F. Hennawi, Frederick B. Davies +11
The nature of "Little Red Dots" and their relation to other forms of accreting supermassive black holes remain an open question. Here we report the discovery of a Little Red Dot at…
Optical and near-infrared spectroscopy of quasars at : public data release and composite spectrum
Silvia Onorato, Joseph F. Hennawi, Jan-Torge Schindler +18
We present optical and near-infrared (NIR) spectroscopic observations for a sample of quasars at with absolute magnitudes at à in the range $-28.82…
Extreme Deconvolution Reimagined: Conditional Densities via Neural Networks and an Application in Quasar Classification
Yi Kang, Joseph F. Hennawi, Jan-Torge Schindler +2
Density estimation is a fundamental problem that arises in many areas of astronomy, with applications ranging from selecting quasars using color distributions to characterizing ste…
