Kavli Affiliate: Renxin Xu | First 5 Authors: Jie Lin, Chunqian Li, Weiyang Wang, Heng Xu, Jinchen Jiang | Summary: We report the discovery of a dark companion to 2MASS J15274848+3536572 with an orbital period of 6.14 hours. Combining the radial velocity of LAMOST observation and the modelling of the multi-band light curve, one has […]

Kavli Affiliate: Xian Chen | First 5 Authors: Alejandro Torres-Orjuela, Xian Chen, , , | Summary: Standard sirens — gravitational wave (GW) sources with an electromagnetic (EM) counterpart — can be used to measure the Hubble constant directly which should help to ease the existing Hubble tension. However, if the source is moving, a relativistic […]

Kavli Affiliate: Jing Wang | First 5 Authors: En-Ze Shao, Kai Liu, Hao Xie, Kaiqi Geng, Keke Bai | Summary: Metal chalcogenide is a promising material for studying novel underlying physical phenomena and nanoelectronics applications. Here, we systematically investigate the crystal structure and electronic properties of the AlSe surface alloy on Al (111) using scanning […]

Kavli Affiliate: Jing Wang | First 5 Authors: Kana Morokuma-Matsui, Kenji Bekki, Jing Wang, Paolo Serra, Yusei Koyama | Summary: We conduct a $^{12}$C$^{16}$O($J$=1-0) (hereafter CO) mapping survey of 64 galaxies in the Fornax cluster using the ALMA Morita array in cycle 5. CO emission is detected from 23 out of the 64 galaxies. Our […]

Kavli Affiliate: Ke Wang | First 5 Authors: Praveen Ravirathinam, Rahul Ghosh, Ke Wang, Keyang Xuan, Ankush Khandelwal | Summary: Creating separable representations via representation learning and clustering is critical in analyzing large unstructured datasets with only a few labels. Separable representations can lead to supervised models with better classification capabilities and additionally aid in […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Anuvab Banerjee, Vibhore Negi, Ravi Joshi, Nagendra Kumar, Paul J. Wiita | Summary: We investigate the possible presence of quasi-periodic oscillation (QPO) signals in 2103 blazars from the Zwicky Transient Facility (ZTF) time-domain survey. We detect a low-frequency QPO signal in five blazars observed over these […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous, Jessie Runnoe, Jonathan R. Trump | Summary: We report the discovery of a new `changing-look’ active galactic nucleus (CLAGN) event, in the quasar SDSS J162829.17+432948.5 at z=0.2603, identified through repeat spectroscopy from the fifth Sloan Digital Sky Survey (SDSS-V). Optical photometry […]
