Kavli Affiliate: Ran Wang | First 5 Authors: Yunjing Wu, Zheng Cai, Marcel Neeleman, Kristian Finlator, Shiwu Zhang | Summary: The physical and chemical properties of the circumgalactic medium (CGM) at $zgtrsim6$ have been studied successfully through the absorption in the spectra of background Quasi-Stellar Objects (QSOs). One of the most crucial questions is to […]
Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Nishant Mishra, Nickolay Gnedin, , , | Summary: We explore the evolution of the flux power spectrum in the Cosmic Reionization On Computers (CROC) simulations. We find that, contrary to some previous studies, the shape of the flux power spectrum is rather insensitive to the timing of […]
Kavli Affiliate: Subo Dong | First 5 Authors: E. Callis, M. Fraser, A. Pastorello, Subo Dong, S. J. Brennan | Summary: We present spectroscopy and photometry of SN 2018zd, a Type IIP core-collapse supernova with signatures of interaction with circumstantial material in its earliest spectra. High ionization lines, the earmark of shock breakout, are not […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Samuel Passaglia, Misao Sasaki, , , | Summary: We show that primordial black holes can be produced from the collapse of large isocurvature perturbations of the cold dark matter. We develop a novel procedure to compute the resulting black hole abundance by studying matched perturbations of matter-only […]

Kavli Affiliate: Lijing Shao | First 5 Authors: Yong Gao, Xiao-Yu Lai, Lijing Shao, Ren-Xin Xu, | Summary: The strong interactions at low energy scales determine the state of the supranuclear matter in the pulsar-like compact objects. It is proposed that the bulk strong matter could be composed of strangeons, which are quark clusters with […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Dara Storer, Joshua S. Dillon, Daniel C. Jacobs, Miguel F. Morales, Bryna J. Hazelton | Summary: We present a framework for identifying and flagging malfunctioning antennas in large radio interferometers. We outline two distinct categories of metrics designed to detect outliers along known failure modes of […]
Kavli Affiliate: Gary A. Steele | First 5 Authors: Shumpei Masuda, Jacob Koenig, Gary A. Steele, , | Summary: Quantum information processing requires fast manipulations of quantum systems in order to overcome dissipative effects. We propose a method to accelerate quantum dynamics and obtain a target state in a shorter time relative to unmodified dynamics, […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Arka Banerjee, Susmita Adhikari, Yao-Yuan Mao, Risa H. Wechsler | Summary: Given recent developments in our understanding of the Large Magellanic Cloud’s (LMC) impact on the Milky Way’s (MW) dark matter subhalo population, we compare the signatures of dark matter and baryonic physics […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: This companion paper to arXiv:2109.00065 explores the interpretation of $AdS_3/CFT_2$ duality for $k=(R_{AdS}/lstr)^2<1$ in terms of "non-critical little string theory". We review the underlying fivebrane structure of 1/2-BPS backgrounds for string theory in both the critical dimension and […]
