Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We begin the study of categorifications of Donaldson-Thomas invariants associated with Hilbert schemes of points on the three-dimensional affine space, which we call DT categories. The DT category is defined to be the category of matrix factorizations on the […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jubee Sohn, Margaret J. Geller, Mark Vogelsberger, Josh Borrow, | Summary: We explore the redshift evolution of the dynamical properties of massive clusters and their brightest cluster galaxies (BCGs) at $z < 2$ based on the IllustrisTNG-300 simulation. We select 270 massive clusters with $M_{200} < 10^{14}~{rm […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Chitraang Murdia, Yasunori Nomura, Kyle Ritchie, , | Summary: We describe two different, but equivalent semiclassical views of black hole physics in which the equivalence principle and unitarity are both accommodated. In one, unitarity is built-in, while the black hole interior emerges only effectively as a collective […]

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Philippe Landry, Salvatore Vitale, , | Summary: Neutron star-black hole (NSBH) mergers detected in gravitational-waves have the potential to shed light on supernova physics, the dense matter equation of state, and the astrophysical processes that power their potential electromagnetic counterparts. We use the population of […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Lingfei Xuan, Wenxuan Wang, Tianxiang Zhang, Jiangyun Li | Summary: The contextual information is critical for various computer vision tasks, previous works commonly design plug-and-play modules and structural losses to effectively extract and aggregate the global context. These methods utilize fine-label to optimize the model […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Kirsten Harth, Dmitry Puzyrev, Ralf Stannarius, | Summary: Soft smooth particles in silo discharge show peculiar characteristics, including, for example, non-permanent clogging and intermittent flow. This paper describes a study of soft, low-frictional hydro-gel spheres in a quasi-2D silo. We enforce a more competitive behavior […]
Kavli Affiliate: Eric Miller | First 5 Authors: Renato A. Dupke, Yolanda Jimenez-teja, Yuanyuan Su, Eleazar R. Carrasco, Anton M. Koekemoer | Summary: Fossil groups (FG) of galaxies still present a puzzle to theories of structure formation. Despite the low number of bright galaxies, they have relatively high velocity dispersions and ICM temperatures often corresponding […]
Kavli Affiliate: Melania Nynka | First 5 Authors: Samar Safi-Harb, Brydyn Mac Intyre, Shuo Zhang, Isaac Pope, Shuhan Zhang | Summary: We present a broadband X-ray study of W50 (`the Manatee nebula’), the complex region powered by the microquasar SS 433, that provides a test-bed for several important astrophysical processes. The W50 nebula, a Galactic […]
