X-ray Halos around Massive Galaxies: Data and Theory

Posted by klaurent June 23, 2022MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Akos Bogdan, Mark Vogelsberger, , , | Summary: The presence of gaseous X-ray halos around massive galaxies is a basic prediction of all past and modern structure formation simulations. The importance of these X-ray halos is further emphasized by the fact that they retain signatures of the […]

A non-linear solution to the $S_8$ tension?

Posted by klaurent June 23, 2022July 11, 2022Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Alexandra Amon, George Efstathiou, , , | Summary: Weak galaxy lensing surveys have consistently reported a lower amplitude for the matter fluctuation spectrum, as measured by the $S_8$ parameter, than expected in the $Lambda{rm CDM}$ cosmology favoured by $Planck$. However, the expansion history follows the predictions of […]

Bridging quantum many-body scar and quantum integrability in Ising chains with transverse and longitudinal fields

Posted by klaurent June 23, 2022July 11, 2022UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Xiaoling Cui, , , | Summary: Quantum many-body scar (QMBS) and quantum integrability(QI) have been recognized as two distinct mechanisms for the breakdown of eigenstate thermalization hypothesis(ETH) in an isolated system. In this work, we reveal a smooth route to connect these two ETH-breaking mechanisms […]

Chandra, HST/STIS, NICER, Swift, and TESS Detail the Flare Evolution of the Repeating Nuclear Transient ASASSN-14ko

Posted by klaurent June 22, 2022July 11, 2022MIT

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Anna V. Payne, Katie Auchettl, Benjamin J. Shappee, Christopher S. Kochanek, Patricia T. Boyd | Summary: ASASSN-14ko is a nuclear transient at the center of the AGN ESO 253-G003 that undergoes periodic flares. Optical flares were first observed in 2014 by the All-Sky Automated Survey for […]

Two can play at that game: constraining the role of supernova and AGN feedback in dwarf galaxies with cosmological zoom-in simulations

Posted by klaurent June 22, 2022July 11, 2022Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Sophie Koudmani, Debora Sijacki, Matthew C. Smith, , | Summary: There is growing observational evidence for dwarf galaxies hosting active galactic nuclei (AGN), including hints of AGN-driven outflows in dwarfs. However, in the common theoretical model of galaxy formation, efficient supernova (SN) feedback is the tool of […]

Probable Dormant Neutron Star in a Short-Period Binary System

Posted by klaurent June 22, 2022Peking

Kavli Affiliate: Subo Dong | First 5 Authors: Tsevi Mazeh, Simchon Faigler, Dolev Bashi, Sahar Shahaf, Niv Davidson | Summary: We have identified 2XMM J125556.57+565846.4, at a distance of 600 pc, as a binary system consisting of a normal star and a probable dormant neutron star. Optical spectra exhibit a slightly evolved F-type single star, […]
