Kavli Affiliate: Erin Kara | First 5 Authors: Yerong Xu, Ciro Pinto, Erin Kara, Stefano Bianchi, William Alston | Summary: The time lag between soft and hard X-ray photons has been observed in many active galactic nuclei (AGN) and can reveal the accretion process and geometry around supermassive black holes (SMBHs). High-frequency Fe K and […]
Kavli Affiliate: Norbert Schulz | First 5 Authors: Ioanna Psaradaki, Missagh Mehdipour, Daniele Rogantini, Elisa Costantini, Norbert Schulz | Summary: Cosmic dust plays a crucial role in the evolution of galaxies, significantly influencing star formation and the interstellar medium. However, in active galactic nuclei (AGN), the role and origin of dust remain poorly understood. High-resolution […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Yash Bhargava, Thomas D. Russell, Mason Ng, Arvind Balasubramanian, Liang Zhang | Summary: We present the first X-ray polarization measurement of the neutron star low-mass X-ray binary and Z-source, GX 340$+$0, in the normal branch (NB) using a 200 ks observation with the Imaging X-ray Polarimetric […]

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 […]
