Extragalactic Magnetism with SOFIA (SALSA Legacy Program). VII. A Tomographic View of Far-infrared and Radio Polarimetric Observations through MHD Simulations of Galaxies

Posted by dbos November 10, 2023Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: Sergio Martin-Alvarez, Enrique Lopez-Rodriguez, Tara Dacunha, Susan E. Clark, Alejandro S. Borlaff | Summary: The structure of magnetic fields in galaxies remains poorly constrained, despite the importance of magnetism in the evolution of galaxies. Radio synchrotron and far-infrared (FIR) polarization and polarimetric observations are the best […]

Modeling the Morphology of Fast Radio Bursts and Radio Pulsars with fitburst

Posted by dbos November 10, 2023November 20, 2023MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Emmanuel Fonseca, Ziggy Pleunis, Daniela Breitman, Ketan R. Sand, Bikash Kharel | Summary: We present a framework for modeling astrophysical pulses from radio pulsars and fast radio bursts (FRBs). This framework, called fitburst, generates synthetic representations of dynamic spectra that are functions of several physical and […]

Crosstalk effects in microwave SQUID multiplexed TES bolometer readout

Posted by dbos November 9, 2023November 20, 2023Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: John C. Groh, Zeeshan Ahmed, Shawn W. Henderson, Johannes Hubmayr, John A. B. Mates | Summary: Transition-edge sensor (TES) bolometers are broadly used for background-limited astrophysical measurements from the far-infrared to mm-waves. Many planned future instruments require increasingly large detector arrays, but their scalability is limited by […]

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

Posted by dbos November 9, 2023November 20, 2023Peking

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 November 9, 2023MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Adam Ingram, Niek Bollemeijer, Alexandra Veledina, Michal Dovciak, Juri Poutanen | Summary: We report on a 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). This is the first time it has been possible […]
