Kavli Affiliate: Taizan Watari | First 5 Authors: Masaki Okada, Taizan Watari, , , | Summary: A characterization of rational superconformal field theories (SCFTs) on 1+1 dimensions with Ricci-flat Kahler targets was proposed by S. Gukov and C. Vafa in terms of the Hodge structure of the target space. The article [arXiv:2205.10299] refined this idea […]
Kavli Affiliate: Sarah N. T. Heine | First 5 Authors: Joseph S. Adams, Robert Baker, Simon R. Bandler, Noemie Bastidon, Daniel Castro | Summary: The flight of the Micro-X sounding rocket on July 22, 2018 marked the first operation of Transition-Edge Sensors and their SQUID readouts in space. The instrument combines the microcalorimeter array with […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Yanan Wang, Ranieri D. Baldi, Santiago del Palacio, Muryel Guolo, Xiaolong Yang | Summary: AT 2019avd is a nuclear transient detected from infrared to soft X-rays, though its nature is yet unclear. The source has shown two consecutive flaring episodes in the optical and the infrared […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Tamara Evstafyeva, Ulrich Sperhake, Thomas Helfer, Robin Croft, Miren Radia | Summary: We present a generalization of the curative initial data construction derived for equal-mass compact binaries in Helfer {it et al} (2019 Phys. Rev. D 99 044046; 2022 Class. Quantum Grav. 39 074001) to arbitrary mass […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Elise Darragh-Ford, John F. Wu, Yao-Yuan Mao, Risa H. Wechsler, Marla Geha | Summary: We introduce the DESI LOW-Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method. Our selection consists of a […]
Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Yukta Ajay, Muryel Guolo, Dheeraj Pasham, , | Summary: We present multiwavelength analyses of an active optical transient AT2021fxu which shows the appearance of previously absent broad emission lines in a recent optical spectrum, suggesting a Changing-look (CL) Active Galactic Nucleus (AGN). During the spectral transition, the […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Jiawen Fan, Hanjue Zhu, Camille Avestruz, Nickolay Y. Gnedin, | Summary: Lyman Limit Systems (LLSs) are dense hydrogen clouds with high enough HI column densities ($N_{rm HI}$) to absorb Lyman continuum photons emitted from distant quasars. Their high column densities imply an origin in dense environments; […]

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Yunchong Zhang, Viraj Manwadkar, Michael D. Gladders, Gourav Khullar, Håkon Dahle | Summary: We report the discovery of five bright strong gravitationally lensed galaxies at $3 < z < 4$: COOLJ0101$+$2055 ($z = 3.459$), COOLJ0104$-$0757 ($z = 3.480$), COOLJ0145$+$1018 ($z = 3.310$), COOLJ0516$-$2208 ($z = 3.549$), […]
