Kavli Affiliate: Wayne Hu | First 5 Authors: Rayne Liu, Wayne Hu, Huangyu Xiao, , | Summary: Wave or fuzzy dark matter produced with high momenta behaves in many ways like hot particle dark matter while also possessing seemingly different phenomenology due to wave interference. We develop wave perturbation theory to show that white noise […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Eleonora Di Valentino, Jackson Levi Said, Adam Riess, Agnieszka Pollo, Vivian Poulin | Summary: The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades. This concordance model is constructed by […]
Fangzhou Jiang, Jinning Liang, Bingcheng Jin, Zeyu Gao, Weichen Wang | Summary: [[{“value”:”Giant bulgeless disk galaxies, theoretically expected to be rare in the early Universe, have been confirmed by the James Webb Space Telescope (JWST) to exist as early as 2 billion years after the Big Bang. These morphologically extreme systems offer valuable insights into […]
Kavli Affiliate: Bradford A. Benson | First 5 Authors: Arnab Sarkar, Michael McDonald, Lindsey Bleem, Mark Bautz, Bradford A. Benson | Summary: We present joint South Pole Telescope (SPT) and XMM-Newton observations of 8 massive galaxy clusters (0.8–1.7$times$10$^{15}$ M$_{odot}$) spanning a redshift range of 0.16 to 0.35. Employing a novel SZ+X-ray fitting technique, we effectively […]
Tingwei Shen, Xuejian Shen, Huangyu Xiao, Mark Vogelsberger, Fangzhou Jiang | Summary: [[{“value”:”Observations of supermassive black holes (SMBHs) at high redshifts challenge standard seeding scenarios. We examine a dissipative self-interacting dark matter (dSIDM) model in which gravothermal collapse leads to the formation of massive BH seeds ab initio. We utilize a semi-analytical framework to predict […]
Fangzhou Jiang, Zixiang Jiang, Haonan Zheng, Luis C. Ho, Kohei Inayoshi | Summary: [[{“value”:”We present a statistical study on the formation and growth of black holes (BHs) seeded by gravothermal core-collapse of self-interacting dark matter (SIDM) halos at high redshifts, using a semi-analytical framework based on Monte-Carlo merger trees. We demonstrate that BH formation via […]

Kavli Affiliate: Joshua Frieman | First 5 Authors: Anowar J. Shajib, Nafis Sadik Nihal, Chin Yi Tan, Vedant Sahu, Simon Birrer | Summary: Strong gravitational lensing is a powerful tool for probing the internal structure and evolution of galaxies, the nature of dark matter, and the expansion history of the Universe, among many other scientific […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Seungjae Lee, Hyung Mok Lee, Ji-hoon Kim, Rainer Spurzem, Jongsuk Hong | Summary: We investigate the evolution of star clusters containing intermediate-mass black hole (IMBH) of $300$ to $5000 mathrm{M}_odot$, focusing on the formation and evolution of IMBH-stellar mass black holes (SBHs; $M_{rm BH} lesssim 10^2 mathrm{M}_odot$) […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Zeeshan Ahmed, Frank Seide, Zhe Liu, Rastislav Rabatin, Jachym Kolar | Summary: Simultaneous or streaming machine translation generates translation while reading the input stream. These systems face a quality/latency trade-off, aiming to achieve high translation quality similar to non-streaming models with minimal latency. We propose an approach […]
