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

Posted by dbos Peking

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

Posted by dbos Peking

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 […]

Low-energy Explosions in a Gravitational Field: Implications for Sub-energetic Supernovae and Fast X-ray Transients

Posted by dbos MIT

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Daniel A. Paradiso, Eric R. Coughlin, Jonathan Zrake, Dheeraj R. Pasham, | Summary: Observations and theory suggest that core-collapse supernovae can span a range of explosion energies, and when sub-energetic, the shockwave initiating the explosion can decelerate to speeds comparable to the escape speed of the […]

Modeling molecular hydrogen in low metallicity galaxies

Posted by dbos Chicago

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Ava Polzin, Andrey V. Kravtsov, Vadim A. Semenov, Nickolay Y. Gnedin, | Summary: We use a suite of hydrodynamics simulations of the interstellar medium (ISM) within a galactic disk, which include radiative transfer, a non-equilibrium model of molecular hydrogen, and a realistic model for star formation […]
