Kavli Affiliate: Steven W. Allen | First 5 Authors: Maya Benyas, Jordan Pfeifer, Adam B. Mantz, Steven W. Allen, Elise Darragh-Ford | Summary: The X-ray morphologies of clusters of galaxies display significant variations, reflecting their dynamical histories and the nonlinear dependence of X-ray emissivity on the density of the intracluster gas. Qualitative and quantitative assessments […]
Kavli Affiliate: Jia Liu | First 5 Authors: Minghong Fang, Zifan Zhang, Hairi, Prashant Khanduri, Jia Liu | Summary: Federated learning (FL) enables multiple clients to collaboratively train machine learning models without revealing their private training data. In conventional FL, the system follows the server-assisted architecture (server-assisted FL), where the training process is coordinated by […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Isabella Lamperti, Santiago Arribas, Michele Perna, Bruno RodrÃguez Del Pino, Chiara Circosta | Summary: We present JWST NIRSpec observations in IFS mode of the galaxy GS5001 at redshift z=3.47, the brightest member of a candidate protocluster in the GOODS-S field. The data cover a field of view […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Eric Zhang, Laura V Sales, Federico Marinacci, Paul Torrey, Mark Vogelsberger | Summary: Simulations of galaxy formation are mostly unable to resolve the energy-conserving phase of individual supernova events, having to resort to subgrid models to distribute the energy and momentum resulting from stellar feedback. However, the […]

Kavli Affiliate: Avi Shporer | First 5 Authors: Molly Nies, Ismael Mireles, François Bouchy, Diana Dragomir, Belinda A. Nicholson | Summary: We report the discovery and validation of HD 21520 b, a transiting planet found with TESS and orbiting a bright G dwarf (V=9.2, $T_{eff} = 5871 pm 62$ K, $R_{star} = 1.04pm 0.02, R_{odot}$). […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Sofia V. Forsblom, Sergey S. Tsygankov, Juri Poutanen, Victor Doroshenko, Alexander A. Mushtukov | Summary: Recent observations of X-ray pulsars (XRPs) performed by the Imaging X-ray Polarimetry Explorer (IXPE) have made it possible to investigate the intricate details of these objects in a new way, thanks to […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Zhen Cao, F. Aharonian, Q. An, Axikegu, Y. X. Bai | Summary: In this work we try to search for signals generated by ultra-heavy dark matter at the Large High Altitude Air Shower Observatory (LHAASO) data. We look for possible gamma-ray by dark matter annihilation or […]
