The Subaru HSC Galaxy Clustering with Photometric Redshift I: Dark Halo Masses Versus Baryonic Properties of Galaxies at 0.3<z<1.4
Shogo Ishikawa, Nobunari Kashikawa, Masayuki Tanaka +8
We present the clustering properties of low- galaxies selected by the Hyper Suprime-Cam Subaru Strategic Program Wide layer over deg. The wide-field and…
Could the black hole singularity be a field singularity?
Guillem Domènech, Atsushi Naruko, Misao Sasaki +1
In the wake of interest to find black hole solutions with scalar hair, we investigate the effects of disformal transformations on static spherically symmetric space-times with a no…
High Q mg-scale monolithic pendulum for quantum-limited gravity measurements
Seth B. Cataño-Lopez, Jordy G. Santiago-Condori, Keiichi Edamatsu +1
We present the development of a high monolithic silica pendulum weighing 7 mg. The measured value for the pendulum mode at 2.2 Hz was . To the best of our kn…
The BAT AGN Spectroscopic Survey -- XVIII. Searching for Supermassive Black Hole Binaries in the X-rays
Tingting Liu, Michael Koss, Laura Blecha +15
Theory predicts that a supermassive black hole binary (SMBHB) could be observed as a luminous active galactic nucleus (AGN) that periodically varies on the order of its orbital tim…
Tracing the co-evolution path of super massive black holes and spheroids with AKARI-selected ultra-luminous IR galaxies at intermediate redshifts
Xiao-Yang Chen, Masayuki Akiyama, Kohei Ichikawa +6
We present the stellar population and ionized-gas outflow properties of ultra-luminous IR galaxies (ULIRGs) at 0.1-1.0, which are selected from AKARI FIR all-sky survey. We co…
Eigenvalues of two-state quantum walks induced by the Hadamard walk
Shimpei Endo, Takako Endo, Takashi Komatsu +1
Existence of the eigenvalues of the discrete-time quantum walks is deeply related to localization of the walks. We revealed the distributions of the eigenvalues given by the splitt…
Diagnosing Cosmic Ray Modified Shocks with H α Polarimetry
Jiro Shimoda, J. Martin Laming
A novel diagnostic of cosmic-ray modified shocks by polarimetry of H emissions is suggested. In a cosmic-ray modified shock, the pressure of cosmic rays is sufficiently high co…
The first astrophysical result of HISAKI: a search for the EUV He I lines a massive cool core cluster at z=0.7
Yuanyuan Su, Tomoki Kimura, Ralph Kraft +6
Molecular cold gas and star formation have been observed at centers of cool-core clusters, albeit at a level much smaller than expected from the classic cooling model. Feedback fro…
NuSTAR Discovery of Dead Quasar Engine in Arp 187
Kohei Ichikawa, Taiki Kawamuro, Megumi Shidatsu +7
Recent active galactic nucleus (AGN) and quasar surveys have revealed a population showing rapid AGN luminosity variability by a factor of . Here we present the most drasti…
BAT AGN Spectroscopic Survey -- XIII. The nature of the most luminous obscured AGN in the low-redshift universe
Rudolf E. Bär, Benny Trakhtenbrot, Kyuseok Oh +18
We present a multi wavelength analysis of 28 of the most luminous low-redshift narrow-line, ultra-hard X-ray selected active galactic nuclei (AGN) drawn from the 70 month Swift/BAT…
Stochastic inflation with an extremely large number of -folds
Naoya Kitajima, Yuichiro Tada, Fuminobu Takahashi
We propose a class of single-field, slow-roll inflation models in which a typical number of -folds can be extremely large. The key point is to introduce a very shallow local min…
Multi-messenger tests of cosmic-ray acceleration in radiatively inefficient accretion flows
Shigeo S. Kimura, Kohta Murase, Peter Mészáros
The cores of active galactic nuclei (AGNs) have been suggested as the sources of IceCube neutrinos, and recent numerical simulations have indicated that hot AGN coronae of Seyfert…
WISE Discovery of Mid-infrared Variability in Massive Young Stellar Objects
Mizuho Uchiyama, Kohei Ichikawa
We systematically investigate the mid-infrared (MIR; m) time variability of uniformly selected massive young stellar objects (MYSOs) from the Red MSX Source (RMS)…
Atto-Nm Torque Sensing with a Macroscopic Optomechanical Torsion Pendulum
Kentaro Komori, Yutaro Enomoto, Ching Pin Ooi +5
Precise measurements of the displacement of, and force acting on, a mechanical oscillator can be performed by coupling the oscillator to an optical cavity. Brownian thermal forces…
A NuSTAR and XMM-Newton Study of the Two Most Actively Star-forming Green Pea Galaxies (SDSS J0749+3337 and SDSS J0822+2241)
Taiki Kawamuro, Yoshihiro Ueda, Kohei Ichikawa +4
We explore X-ray evidence for the presence of active galactic nuclei (AGNs) in the two most actively star-forming Green Pea galaxies (GPs), SDSS J0749+3337 and SDSS J0822+2241, whi…
Fluctuation of the background sky in the Hubble Extremely Deep Field (XDF) and its origin
Toshio Matsumoto, Kohji Tsumura
We performed a fluctuation analysis of the Hubble Extremely Deep Field (XDF) at four optical wavelength bands and found large fluctuations that are significantly brighter than thos…
A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). II. Physical Properties derived from the SED Fitting with Optical, Infrared, and Radio Data
Yoshiki Toba, Takuji Yamashita, Tohru Nagao +14
We present physical properties of radio galaxies (RGs) with 1 mJy discovered by Subaru Hyper Supreme-Cam (HSC) and VLA Faint Images of the Radio Sky at Twenty-C…
ALMA polarimetry measures magnetically aligned dust grains in the torus of NGC 1068
Enrique Lopez-Rodriguez, Almudena Alonso-Herrero, Santiago García-Burillo +7
The obscuring structure surrounding active galactic nuclei (AGN) can be explained as a dust and gas flow cycle that fundamentally connects the AGN with their host galaxies. This st…
