Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Yashvi Sharma, Jesper Sollerman, Shrinivas R. Kulkarni, Takashi J. Moriya, Steve Schulze | Summary: Multi-peaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-sky transient surveys like the Zwicky Transient Facility (ZTF). Here, we present […]

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 […]
