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: Rana X. Adhikari | First 5 Authors: Tuvia Gefen, Rajashik Tarafder, Rana X. Adhikari, Yanbei Chen, | Summary: Current laser-interferometric gravitational wave detectors suffer from a fundamental limit to their precision due to the displacement noise of optical elements contributed by various sources. Several schemes for Displacement-Noise Free Interferometers (DFI) have been proposed […]
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: Kristin A. Persson | First 5 Authors: Ruo Xi Yang, Matthew K. Horton, Jason Munro, Kristin A. Persson, | Summary: An optical absorption spectrum constitutes one of the most fundamental material characteristics, with relevant applications ranging from material identification to energy harvesting and optoelectronics. However, the database of both experimental and computational spectra […]
Kavli Affiliate: Austin J. Minnich | First 5 Authors: Bekari Gabritchidze, Kieran A. Cleary, Anthony C. Readhead, Austin J. Minnich, | Summary: We report the on-wafer characterization of $S$-parameters and microwave noise temperature ($T_{50}$) of discrete metamorphic InGaAs high electron mobility transistors (mHEMTs) at 40 K and 300 K and over a range of drain-source […]
