Dark Matter Isocurvature from Curvature

Posted by dbos November 28, 2023December 11, 2023Chicago

Kavli Affiliate: Wayne Hu | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Isocurvature fluctuations, where the relative number density of particle species spatially varies, can be generated from initially adiabatic or curvature fluctuations if the various species fall out of or were never in thermal equilibrium. The freezing of the thermal relic […]

Dynamics and spin alignment in massive, gravito-turbulent circumbinary discs around supermassive black hole binaries

Posted by dbos November 28, 2023December 11, 2023Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Martin A. Bourne, Davide Fiacconi, Debora Sijacki, Joanna M. Piotrowska, Sophie Koudmani | Summary: Parsec-scale separation supermassive black hole binaries in the centre of gas-rich galaxy merger remnants could be surrounded by massive circumbinary discs (CBDs). Black hole mass and spin evolution during the gas-rich binary inspiral […]

Predicting the Age of Astronomical Transients from Real-Time Multivariate Time Series

Posted by dbos November 28, 2023MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Hali Huang, Daniel Muthukrishna, Prajna Nair, Zimi Zhang, Michael Fausnaugh | Summary: Astronomical transients, such as supernovae and other rare stellar explosions, have been instrumental in some of the most significant discoveries in astronomy. New astronomical sky surveys will soon record unprecedented numbers of transients as sparsely […]

Galaxy Formation and Symbiotic Evolution with the Inter-Galactic Medium in the Age of ELT-ANDES

Posted by dbos November 28, 2023December 11, 2023Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Valentina D’Odorico, James S. Bolton, Lise Christensen, Annalisa De Cia, Erik Zackrisson | Summary: High-resolution absorption spectroscopy toward bright background sources has had a paramount role in understanding early galaxy formation, the evolution of the intergalactic medium and the reionisation of the Universe. However, these studies are […]

Low- and High-velocity ion{O}{6} in Milky Way-like Galaxies: the Role of Stellar Feedback

Posted by dbos November 27, 2023December 11, 2023MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhijie Zhang, Xiaoxia Zhang, Hui Li, Taotao Fang, Qingzheng Yu | Summary: Milky Way-type galaxies are surrounded by a warm-hot gaseous halo containing a considerable amount of baryons and metals. The kinematics and spatial distribution of highly-ionized ion species such as ion{O}{6} can be significantly affected by […]
