Interplay of Compaction, Quenching, and Black Hole Growth in the Most Massive Galaxies since : Insights from JWST and Chandra Data
Novan Saputra Haryana, Masayuki Akiyama, Abdurro'uf +16
The buildup of dense stellar cores is expected to mark an important transition in the star-formation and black-hole growth of massive galaxies. Using spatially resolved spectral en…
A z ~ 0.4 Galaxy Reflecting the high-redshift Little Red Dots: An Extended Starburst with an Overmassive Black Hole
Xiaoyang Chen, Kohei Ichikawa, Masayuki Akiyama +10
One of the most remarkable discoveries of JWST is a population of compact, red sources at z > 4, commonly referred to as Little Red Dots (LRDs). Spectroscopic identifications repor…
Unveiling a Population of Strong Galaxy-Galaxy Lensed Faint Dusty Star-Forming Galaxies
Ting-Kai Yang, Chian-Chou Chen, Zhen-Kai Gao +10
The measurements of the number density of galaxy-galaxy strong lenses can be used to put statistical constraints on the foreground mass distributions. Dusty galaxies uncovered in s…
Observational Properties of AGN Obscuration During the Peak of Accretion Growth
Bovornpratch Vijarnwannaluk, Masayuki Akiyama, Malte Schramm +11
We investigated the gas obscuration and host galaxy properties of active galactic nuclei (AGN) during the peak of cosmic accretion growth of supermassive black holes (SMBHs) at red…
The Obscured Fraction of Quasars at Cosmic Noon
Bovornpratch Vijarnwannaluk, Masayuki Akiyama, Malte Schramm +6
Statistical studies of X-ray selected Active Galactic Nuclei (AGN) indicate that the fraction of obscured AGN increases with increasing redshift, and the results suggest that a sig…
Finding of a population of active galactic nuclei showing a significant luminosity decline in the past yrs
J. Pflugradt, K. Ichikawa, M. Akiyama +4
Recent observations have revealed an interesting active galactic nuclei (AGN) subclass that shows strong activity at large scales ( kpc) but weaker at small scales ( pc…
