Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Dheeraj Pasham, Shubham Kejriwal, Eric Coughlin, Vojtěch Witzany, Alvin J. K. Chua | Summary: Quasi-periodic eruptions (QPEs) are recurring bursts of soft X-rays from the nuclei of galaxies. Their physical origin is currently a subject of debate, with models typically invoking an orbiter around a massive black […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Thomas C. Abbott, Andrew V. Zwaniga, Charanjot Brar, Victoria M. Kaspi, Emily Petroff | Summary: We present frb-voe, a publicly available software package that enables radio observatories to broadcast fast radio burst (FRB) alerts to subscribers through low-latency virtual observatory events (VOEvents). We describe a use-case […]
Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, David P. Huenemoerder, , , | Summary: We present conditions for which X-ray spectra can be “unfolded” to present accurate representation of the true source spectra. The method we use to unfold the data is implemented in the textit{Interactive Spectral Interpretation Software} citep{Houck2000} […]
Kavli Affiliate: Erin Kara | First 5 Authors: Ethan R. Partington, Edward M. Cackett, Rick Edelson, Keith Horne, Jonathan Gelbord | Summary: The Seyfert 1 AGN Fairall 9 was targeted by NICER, Swift, and ground-based observatories for a $sim$1000-day long reverberation mapping campaign. The following analysis of NICER spectra taken at a two-day cadence provides […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Dmitry A. Prokhorov, Yi-Jung Yang, Riccardo Ferrazzoli, Jacco Vink, Patrick Slane | Summary: Synchrotron X-ray emission has been detected from nearly a dozen young supernova remnants (SNRs). X-rays of synchrotron origin exhibit linear polarization in a regular, non-randomly oriented magnetic field. The significant polarized X-ray emission […]
Kavli Affiliate: Sara Seager | First 5 Authors: Rosa E. Keers, Alexander I. Shapiro, Nadiia M. Kostogryz, Ana Glidden, Prajwal Niraula | Summary: Stellar limb darkening must be properly accounted for to accurately determine the radii of exoplanets at various wavelengths. The standard approach to address limb darkening involves either using laws with coefficients from […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Antonio Herrera-Martin, Radu V. Craiu, Gwendolyn M. Eadie, David C. Stenning, Derek Bingham | Summary: An important task in the study of fast radio bursts (FRBs) remains the automatic classification of repeating and non-repeating sources based on their morphological properties. We propose a statistical model that […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Danté M. Hewitt, Mohit Bhardwaj, Alexa C. Gordon, Aida Kirichenko, Kenzie Nimmo | Summary: We present the localization and host galaxy of FRB 20190208A, a repeating source of fast radio bursts (FRBs) discovered using CHIME/FRB. As part of the PRECISE repeater localization program on the EVN, […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Kaley Brauer, Andrew Emerick, Jennifer Mead, Alexander P. Ji, John H. Wise | Summary: The AEOS project introduces a series of high-resolution cosmological simulations that model star-by-star chemical enrichment and galaxy formation in the early Universe, achieving 1 pc resolution. These simulations capture the complexities of galaxy […]
