A Nitrogen-rich AGN Powering a Large Ionizing Bubble at z=8.63

Takahiro Morishita, Massimo Stiavelli, Charlotte A. Mason +5

We report the detection of Ly in CANUCS-LRD-z8.6, a recently discovered AGN at z = 8.63 by Tripodi et al. (2024), in new NIRSpec/MSA G140H/F070LP observations. We detect broad L…

A stellar dynamical mass measurement of an inactive black hole at redshift 2

Andrew B. Newman, Meng Gu, Sirio Belli +34

Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…

Enhanced strong-lensing model of MACS~J0138.02155 based on new JWST and VLT/MUSE observations

Ana Acebron, Pietro Bergamini, Piero Rosati +10

We present a new parametric strong lensing analysis of the galaxy cluster MACS J0138.0-2155 at z = 0.336, the first known to show two multiply-imaged supernova (SN) siblings, SN Re…

Accelerating lensed quasar discovery and modeling with physics-informed variational autoencoders

Irham T. Andika, Stefan Schuldt, Sherry H. Suyu +5

Strongly lensed quasars provide valuable insights into the rate of cosmic expansion, the distribution of dark matter in foreground deflectors, and the characteristics of quasar hos…

The next step in galaxy cluster strong lensing: modeling the surface brightness of multiply-imaged sources

Ana Acebron, Claudio Grillo, Sherry H. Suyu +12

Overcoming both modeling and computational challenges, we present, for the first time, the extended surface-brightness distribution model of a strongly-lensed source in a complex g…

Using Convolutional Neural Networks to Search for Strongly Lensed Quasars in KiDS DR5

Zizhao He, Rui Li, Yiping Shu +13

Gravitationally strongly lensed quasars (SL-QSO) offer invaluable insights into cosmological and astrophysical phenomena. With the data from ongoing and next-generation surveys, th…
