ALMA gas-dynamical mass measurement of the supermassive black hole in the red nugget relic galaxy PGC 11179

Kavli Affiliate: Luis Ho | First 5 Authors: Jonathan H. Cohn, Maeve Curliss, Jonelle L. Walsh, Kyle M. Kabasares, Benjamin D. Boizelle | Summary: We present 0$.!!^{primeprime}22$-resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of CO(2$-$1) emission from the circumnuclear gas disk in the red nugget relic galaxy PGC 11179. The disk shows regular rotation, with […]

Dual-Band Observations of the Asymmetric Ring around CIDA 9A: Dead or Alive?

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Daniel Harsono, Feng Long, Paola Pinilla, Alessia A. Rota, Carlo F. Manara | Summary: While the most exciting explanation of the observed dust asymmetries in protoplanetary disks is the presence of protoplanets, other mechanisms can also form the dust features. This paper presents dual-wavelength Atacama Large […]

Ray-tracing simulations of the Soft X-ray Scattered Emission in obscured Active Galactic Nuclei

Kavli Affiliate: Claudio Ricci | First 5 Authors: Jeffrey McKaig, Claudio Ricci, Stéphane Paltani, K. K. Gupta, Nicholas P. Abel | Summary: Most Active Galactic Nuclei (AGN) in the local Universe are obscured. In these obscured AGN an excess is usually observed in the soft X-rays below ~2 keV above the absorbed X-ray continuum. This […]

From Halos to Galaxies. VII. The Connections Between Stellar Mass Growth History, Quenching History and Halo Assembly History for Central Galaxies

Kavli Affiliate: Yingjie Peng | First 5 Authors: Cheqiu Lyu, Yingjie Peng, Yipeng Jing, Xiaohu Yang, Luis C. Ho | Summary: The assembly of galaxies over cosmic time is tightly connected to the assembly of their host dark matter halos. We investigate the stellar mass growth history and the chemical enrichment history of central galaxies […]

Constraints on charged black holes from merger-ringdown signals in GWTC-3 and prospects for the Einstein Telescope

Kavli Affiliate: Lijing Shao | First 5 Authors: Hua-Peng Gu, Hai-Tian Wang, Lijing Shao, , | Summary: Whether astrophysical black holes (BHs) can have charge is a question to be addressed by observations. In the era of gravitational wave (GW) astronomy, one can constrain the charge of a merged BH remnant using the merger-ringdown signal […]

Till the core collapses: the evolution and properties of self-interacting dark matter subhalos

Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du, Shengqi Yang, Andrew Benson | Summary: [[{“value”:”One of the hottest questions in the cosmology of self-interacting dark matter (SIDM) is whether scatterings can induce detectable core-collapse in halos by the present day. Because gravitational tides can accelerate core-collapse, the most promising targets to observe core-collapse are […]
