ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions-IX. A pilot study towards IRDC G034.43+00.24 on multi-scale structures and gas kinematics

Kavli Affiliate: Ke Wang | First 5 Authors: Hong-Li Liu, Anandmayee Tej, Tie Liu, Paul F. Goldsmith, Amelia Stutz | Summary: We present a comprehensive study of the gas kinematics associated with density structures at different spatial scales in the filamentary infrared dark cloud, G034.43+00.24 (G34). This study makes use of the H13CO+ (1-0) molecular […]

Gravitational Casimir Effect in Inspiralling Neutron Star Binary

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, , , , | Summary: Currently, the discussions and investigations for the vacuum energy is drawing great both theoretical and experimental attention. The vacuum states of variety of fields, subject to special boundary conditions, may contribute to non-trivial macroscopic vacuum energy, i.e. the Casimir effect, […]

Massive Galaxy Mergers Have Distinctive Global HI Profiles

Kavli Affiliate: Jing Wang | First 5 Authors: Pei Zuo, Luis C. Ho, Jing Wang, Niankun Yu, Jinyi Shangguan | Summary: The global 21 cm HI emission-line profile of a galaxy encodes valuable information on the spatial distribution and kinematics of the neutral atomic gas. Galaxy interactions significantly influence the HI disk and imprint observable […]

Strong spiral arms drive secular growth of pseudo bulges in disk galaxies

Kavli Affiliate: Jing Wang | First 5 Authors: Si-Yue Yu, Dewang Xu, Luis C. Ho, Jing Wang, Wei-Bo Kao | Summary: Spiral-driven instabilities may drive gas inflow to enhance central star formation in disk galaxies. We investigate this hypothesis using the Sloan Digital Sky Survey (SDSS) in a sample of 2779 nearby unbarred star-forming main-sequence […]

Evidence for quasar fast outflows being accelerated at the scale of tens of parsecs

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhicheng He, Guilin Liu, Tinggui Wang, Guobin Mou, Richard Green | Summary: Quasar outflows may play a crucial role in regulating the host galaxy, although the spatial scale of quasar outflows remain a major enigma, with their acceleration mechanism poorly understood. The kinematic information of outflow […]

A multiwavelength-motivated X-ray model for the Circinus Galaxy

Kavli Affiliate: Claudio Ricci | First 5 Authors: Carolina Andonie, Claudio Ricci, Stéphane Paltani, Patricia Arévalo, Ezequiel Treister | Summary: Reprocessed X-ray emission in Active Galactic Nuclei (AGN) can provide fundamental information about the circumnuclear environments of supermassive black holes. Recent mid-infrared studies have shown evidence of an extended dusty structure perpendicular to the torus […]

Dissecting the different components of the modest accretion bursts of the very young protostar HOPS 373

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Sung-Yong Yoon, Gregory J. Herczeg, Jeong-Eun Lee, Ho-Gyu Lee, Doug Johnstone | Summary: Observed changes in protostellar brightness can be complicated to interpret. In our JCMT~Transient monitoring survey, we discovered that a young binary protostar, HOPS 373, is undergoing a modest $30%$ brightness increase at 850 […]

Luminosity function and event rate density of XMM-Newton-selected supernova shock-breakout candidates

Kavli Affiliate: Zhuo Li | First 5 Authors: Hui Sun, He-Yang Liu, Haiwu Pan, Zhu Liu, Dennis Alp | Summary: A dozen X-ray supernova shock breakout (SN SBO) candidates were reported recently based on XMM-Newton archival data, which increased the X-ray selected SN SBO sample by an order of magnitude. Assuming they are genuine SN […]
