Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michael N. Martinez, Kate A. Napier, Aidan P. Cloonan, Ezra Sukay, Katya Gozman | Summary: In the third paper from the COOL-LAMPS Collaboration, we report the discovery of COOL J0542-2125, a gravitationally lensed quasar at $z=1.84$, observed as three images due to an intervening massive galaxy […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: David J. Schlegel, Simone Ferraro, Greg Aldering, Charles Baltay, Segev BenZvi | Summary: In this white paper, we present an experimental road map for spectroscopic experiments beyond DESI. DESI will be a transformative cosmological survey in the 2020s, mapping 40 million galaxies and quasars and capturing […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Kanji Mori, Takashi J. Moriya, Tomoya Takiwaki, Kei Kotake, Shunsaku Horiuchi | Summary: It was recently proposed that exotic particles can trigger a new stellar instability which is analogous to the e-e+ pair instability if they are produced and reach equilibrium in the stellar plasma. In this […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keren Sharon, Guillaume Mahler, T. Emil Rivera-Thorsen, Hakon Dahle, Michael D. Gladders | Summary: We present a strong lensing analysis of the cluster PSZ1 G311.65-18.48, based on Hubble Space Telescope imaging, archival VLT/MUSE spectroscopy, and Chandra X-ray data. This cool-core cluster (z=0.443) lenses the brightest lensed […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Fengwu Sun, Eiichi Egami, Nor Pirzkal, Marcia Rieke, Stefi Baum | Summary: We present a sample of four emission-line galaxies at $z=6.11-6.35$ that were serendipitously discovered using the commissioning data for the JWST/NIRCam wide-field slitless spectroscopy (WFSS) mode. One of them (at $z=6.11$) has been reported previously […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Xuheng Ding, John D. Silverman, Masafusa Onoue, , | Summary: We measure the host galaxy properties of five quasars with $zsim 1.6 – 3.5$ selected from SDSS and AEGIS, which fall within the JWST/HST CEERS survey area. A PSF library is constructed based on stars in […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Angus Beane, Lars Hernquist, Elena D’Onghia, Federico Marinacci, Charlie Conroy | Summary: Elongated bar-like features are ubiquitous in galaxies, occurring at the centers of approximately two-thirds of spiral disks. Due to gravitational interactions between the bar and the other components of galaxies, it is expected that angular […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Lijing Shao, Kent Yagi, , , | Summary: Neutron stars are versatile in their application to studying various important aspects of fundamental physics, in particular strong-field gravity tests and the equation of state for super-dense nuclear matter at low temperatures. However, in many cases these two objectives […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Khanh Pham, Andrey Kravtsov, Viraj Manwadkar, , | Summary: We examine the spatial distribution and orbital pole correlations of satellites in a suite of zoom-in high-resolution dissipationless simulations of Miky Way (MW) sized haloes. We use the measured distribution to estimate the incidence of satellite configurations as […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Philip Mansfield, Yunchong Wang, Xiaolong Du, Susmita Adhikari | Summary: We present Symphony, a compilation of $262$ cosmological, cold dark matter-only zoom-in simulations spanning four decades of host halo mass, from $10^{11}~M_{mathrm{odot}}$ to $10^{15}~M_{mathrm{odot}}$. This compilation includes three existing simulation suites at the […]
