ALMA Sub-parsec Resolution Dense Molecular Line Observations of the NGC 1068 Nucleus
Masatoshi Imanishi, Bernd Vollmer, Yoshiaki Hagiwara +3
We present the results of our ALMA observations of the dense molecular HCN J=4-3 and HCO J=4-3 lines at 1 pc (14 mas) resolution in the nuclear region of…
SHELLQs-JWST: Revealing the Spectra of Extended Emission in 12 z > 6 Quasar Host Galaxies using the JWST NIRSpec Fixed Slit
Camryn L. Phillips, Michael A. Strauss, Masafusa Onoue +15
We present an analysis of the rest frame optical JWST NIRSpec Fixed Slit spectra of extended host galaxy emission in 12 quasars from the Subaru High-z Exploration of Low-Luminosity…
ALMA Deep Field in SSA22: Reconstructed [CII] Luminosity Function at z = 6
Natsuki H. Hayatsu, Rob J. Ivison, Paola Andreani +19
The ADF22 line survey reported detections of two high- line-emitting source candidates above 6-, both of which were shown to be spurious after follow-up observations. We inve…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XXIV. 54 New Quasars and Candidate Obscured Quasars at
Yoshiki Matsuoka, Kazushi Iwasawa, Masafusa Onoue +18
We present spectroscopic identification of 43 quasars and 11 candidate obscured quasars in the epoch of reionization (EoR) at , along with 29 galaxies at simil…
SHELLQs-JWST perspective on the intrinsic mass relation between supermassive black holes and their host galaxies at z > 6
John Silverman, Junyao Li, Xuheng Ding +36
The relation between the masses of supermassive black holes (SMBHs) and their host galaxies encodes information on their mode of growth, especially at the earliest epochs. The Jame…
GATOS. VIII. On the physical origin of the extended MIR emission in AGN
Enrique Lopez-Rodriguez, Cristina Ramos Almeida, Miguel Pereira-Santaella +31
The polar mid-infrared (MIR) emission detected within 10-100s pcs in some active galactic nuclei (AGN) has been associated with dusty winds driven away by radiation pressure. The p…
Overmassive Black holes live in compact galaxies in the early Universe
Yuxuan Wu, Tao Wang, Daizhong Liu +9
A significant population of quasars have been found to exist within the first Gyr of cosmic time. Most of them have high black hole (BH) masses ($M_{\rm BH} \sim 10^{8-10} M_{\odot…
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…
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…
SHELLQs-JWST Unveils the Host Galaxies of 12 Quasars at z>6
Xuheng Ding, Masafusa Onoue, John D. Silverman +35
The advent of JWST has opened new horizons in the study of quasar host galaxies during the reionization epoch (z>6). Building upon our previous initial measurements of stellar ligh…
From Non-Detection to Detection: Atacama Compact Array Mosaic Observations of Faint Extended [C I] Emission in NGC 7679
Tomonari Michiyama, Toshiki Saito, Kouichiro Nakanishi +8
We report the detection of [C I] -- emission in the nearby galaxy NGC 7679 using the Atacama Compact Array (ACA) of the Atacama Large Millimeter/submillimeter Array (…
No Galaxy-Scale [CII] Fast Outflow in the z=6.72 Red Quasar HSC J12050000
Mahoshi Sawamura, Takuma Izumi, Kouichiro Nakanishi +17
HSC 120505.09-000027.9 (J12050000) is one of the highest redshift () dust-reddened quasars (red quasars) known to date. We present an improved analysis of Atacama Large…
