A rest-frame near-IR study of clumps in galaxies at 1 < z < 2 using JWST/NIRCam: connection to galaxy bulges

Kavli Affiliate: Luis C. Ho | First 5 Authors: Boris S. Kalita, John D. Silverman, Emanuele Daddi, Connor Bottrell, Luis C. Ho | Summary: A key question in galaxy evolution has been the importance of the apparent `clumpiness’ of high redshift galaxies. Until now, this property has been primarily investigated in rest-frame UV, limiting our […]

Gaia22dkvLb: A Microlensing Planet Potentially Accessible to Radial-Velocity Characterization

Kavli Affiliate: Subo Dong | First 5 Authors: Zexuan Wu, Subo Dong, Tuan Yi, Zhuokai Liu, Kareem El-Badry | Summary: We report discovering an exoplanet from following up a microlensing event alerted by Gaia. The event Gaia22dkv is toward a nearby disk source at ~2.5 kpc rather than the traditional bulge microlensing fields. Our primary […]

BASS-XL: X-ray variability properties of unobscured Active Galactic Nuclei

Kavli Affiliate: Claudio Ricci | First 5 Authors: Alessia Tortosa, Claudio Ricci, Patricia ArĂ©valo, Michael J. Koss, Franz E. Bauer | Summary: We investigate the X-ray variability properties of Seyfert1 Galaxies belonging to the BAT AGN Spectroscopic Survey (BASS). The sample includes 151 unobscured (N$_{rm H}<10^{22}$ cm$^{-2}$) AGNs observed with XMM-Newton for a total exposure […]

Moment of Inertia for Axisymmetric Neutron Stars in the Standard-Model Extension

Kavli Affiliate: Lijing Shao | First 5 Authors: Yiming Dong, Zexin Hu, Rui Xu, Lijing Shao, | Summary: We develop a consistent approach to calculate the moment of inertia (MOI) for axisymmetric neutron stars (NSs) in the Lorentz-violating Standard-Model Extension (SME) framework. To our knowledge, this is the first relativistic MOI calculation for axisymmetric NSs […]

Probing the Galactic halo with RR Lyrae stars — IV. On the Oosterhoff dichotomy of RR Lyrae stars

Kavli Affiliate: Huawei Zhang | First 5 Authors: Shan Zhang, Gaochao Liu, Yang Huang, Zongfei Lv, Sarah Ann Bird | Summary: We use 3653 (2661 RRab, 992 RRc) RR Lyrae stars (RRLs) with 7D (3D position, 3D velocity, and metallicity) information selected from SDSS, LAMOST, and Gaia EDR3, and divide the sample into two Oosterhoff […]

BASS XXXIV: A Catalog of the Nuclear Mm-wave Continuum Emission Properties of AGNs Constrained on Scales $lesssim$ 100–200 pc

Kavli Affiliate: Claudio Ricci | First 5 Authors: Taiki Kawamuro, Claudio Ricci, Richard F. Mushotzky, Masatoshi Imanishi, Franz E. Bauer | Summary: We present a catalog of the millimeter-wave (mm-wave) continuum properties of 98 nearby ($z <$ 0.05) active galactic nuclei (AGNs) selected from the 70-month Swift/BAT hard X-ray catalog that have precisely determined X-ray […]
