Hidden in Pixels I: Discovery of dual "little red dots" indicates excess clustering on kilo-parsec scales

Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +56

``Little Red Dots'' (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST) and considered to be an early growth phase of supermas…

A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6

Masafusa Onoue, Xuheng Ding, John D. Silverman +45

Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…

Going deeper into the dark with COSMOS-Web: JWST unveils the total contribution of Radio-Selected NIRfaint galaxies to the cosmic Star Formation Rate Density

Fabrizio Gentile, Margherita Talia, Andrea Enia +34

We present the first follow-up with JWST of radio-selected NIRfaint galaxies as part of the COSMOS-Web survey. By selecting galaxies detected at radio frequencies ($S_{\rm 3 GHz}>1…

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…
