Probabilistic Inference of the Structure and Orbit of Milky Way Satellites with Semi-Analytic Modeling

Posted by dbos Peking

Dylan Folsom, Oren Slone, Mariangela Lisanti, Fangzhou Jiang, Manoj Kaplinghat | Summary: [[{“value”:”Semi-analytic modeling furnishes an efficient avenue for characterizing the properties of dark matter halos associated with satellites of Milky Way-like systems, as it easily accounts for uncertainties arising from halo-to-halo variance, the orbital disruption of satellites, baryonic feedback, and the stellar-to-halo mass (SMHM) […]

Tracking the X-ray Polarization of the Black Hole Transient Swift J1727.8-1613 during a State Transition

Posted by dbos MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Adam Ingram, Niek Bollemeijer, Alexandra Veledina, Michal Dovciak, Juri Poutanen | Summary: We report on an observational campaign on the bright black hole X-ray binary Swift J1727.8$-$1613 centered around five observations by the Imaging X-ray Polarimetry Explorer (IXPE). These observations track for the first time the […]
