Aether-SHELLQs: JWST integral-field spectroscopy of candidate obscured quasars at z ~ 6
Yoshiki Matsuoka, Roberto Decarli, Emanuele Paolo Farina +12
We present James Webb Space Telescope (JWST) NIRSpec integral field unit (IFU) observations of six galaxies at , obtained as part of the Aether project (General Observers…
Subaru High- Exploration of Low-Luminosity Quasars (SHELLQs). XXV. Large-scale environments of low-luminosity quasars at traced by Ly emitters
Junya Arita, Nobunari Kashikawa, Yoshiki Matsuoka +18
High- quasars are believed to reside in massive dark matter haloes (DMHs), suggesting that they reside in galaxy overdense regions. However, previous observations have shown a r…
The Journey to Dominance: How BCGs Evolve Differently from Other Massive Galaxies
Marcelo C. Vicentin, Michael A. Strauss, Laerte Sodré +3
We use the L-GALAXIES semi-analytic model to investigate the evolution of Brightest Cluster Galaxies (BCGs) found in clusters at . BCGs are typically located in the c…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) XXII. Chandra observations of narrow-line quasar candidates at z>6
K. Iwasawa, R. Gilli, F. Vito +13
We report on Chandra X-ray observations of four narrow-line quasar candidates at z~6, selected from the SHELLQs project, based on the Subaru Hyper Suprime-Cam survey. These objects…
The Discovery of Little Red Dots in the Local Universe: Signatures of Cool Gas Envelopes
Xiaojing Lin, Xiaohui Fan, Zheng Cai +25
JWST observations have revealed a population of high-redshift "little red dots" (LRDs) that challenge conventional AGN models. We report the discovery of three local LRDs at $z = 0…
SHELLQs. Bridging the Gap: JWST Unveils Obscured Quasars in the Most Luminous Galaxies at z > 6
Yoshiki Matsuoka, Masafusa Onoue, Kazushi Iwasawa +17
The unprecedented sensitivity of the James Webb Space Telescope (JWST) has uncovered a surprisingly abundant population of mildly obscured, low-luminosity active galactic nuclei (A…
