Kavli Affiliate: Herman L. Marshall | First 5 Authors: Fei Xie, Josephine Wong, Fabio La Monaca, Roger W. Romani, Jeremy Heyl | Summary: We report on X-ray polarization measurements of the extra-galactic Crab-like PSR B0540-69 and its Pulsar Wind Nebula (PWN) in the Large Magellanic Cloud (LMC), using a ~850 ks Imaging X-ray Polarimetry Explorer […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Charlie Mace, Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du, Shengqi Yang | Summary: Self-interacting dark matter (SIDM) theory predicts that dark matter halos experience core-collapse, a process where the halo’s inner region rapidly increases in density and decreases in size. The N-body simulations used to […]

Kavli Affiliate: Michael McDonald | First 5 Authors: Cian Roche, Michael McDonald, Josh Borrow, Mark Vogelsberger, Xuejian Shen | Summary: The distribution of offsets between the brightest cluster galaxies of galaxy clusters and the centroid of their dark matter distributions is a promising probe of the underlying dark matter physics. In particular, since this distribution […]
Kavli Affiliate: Lina Necib | First 5 Authors: Cian Roche, Lina Necib, Tongyan Lin, Xiaowei Ou, Tri Nguyen | Summary: The escape velocity profile of the Milky Way offers a crucial and independent measurement of its underlying mass distribution and dark matter properties. Using a sample of stars from Gaia DR3 with 6D kinematics and […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ayush Pandhi, Ziggy Pleunis, Ryan Mckinven, B. M. Gaensler, Jianing Su | Summary: We present a 400-800 MHz polarimetric analysis of 128 non-repeating fast radio bursts (FRBs) from the first CHIME/FRB baseband catalog, increasing the total number of FRB sources with polarization properties by a factor […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Daniel A. Perley, Anna Y. Q. Ho, Michael Fausnaugh, Gavin P. Lamb, Mansi M. Kasliwal | Summary: Classical gamma-ray bursts (GRBs) have two distinct emission episodes: prompt emission from ultra-relativistic ejecta and afterglow from shocked circumstellar material. While both components are extremely luminous in known GRBs, a […]

Kavli Affiliate: Sara Seager | First 5 Authors: Angelica Psaridi, Hugh Osborn, François Bouchy, Monika Lendl, Léna Parc | Summary: We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal it to be a young star with […]
