Kavli Affiliate: Nicola Omodei | First 5 Authors: Krista Lynne Smith, Ryan Ridden-Harper, Michael Fausnaugh, Tansu Daylan, Nicola Omodei | Summary: The TESS exoplanet-hunting mission detected the rising and decaying optical afterglow of GRB 191016A, a long Gamma-Ray Burst (GRB) detected by Swift-BAT but without prompt XRT or UVOT follow-up due to proximity to the […]
Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Rodolfo Ostilla-Mónico, Ryan McKeown, Michael P. Brenner, Shmuel M. Rubinstein, Alain Pumir | Summary: At high Reynolds number, the interaction between two vortex tubes leads to intense velocity gradients, which are at the heart of fluid turbulence. This vorticity amplification comes about through two different instability […]
Kavli Affiliate: Xian Chen | First 5 Authors: Zucheng Gao, Xian Chen, Yi-Ming Hu, Jian-Dong Zhang, Shunjia Huang | Summary: Gravitational lensing of gravitational waves (GWs) is a powerful probe of the matter distribution in the universe. Here we revisit the wave-optics effects induced by dark matter (DM) halos on the GW signals of merging […]
Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Jia Liu, Navin McGinnis, Carlos E. M. Wagner, Xiao-Ping Wang, | Summary: We report on an interesting realization of the QCD axion, with mass in the range $mathcal{O}(10)$ MeV. It has previously been shown that although this scenario is stringently constrained from multiple sources, the […]
Kavli Affiliate: Donald G. York | First 5 Authors: Britt F. Lundgren, Samantha Creech, Gabriel Brammer, Nathan Kirse, Matthew Peek | Summary: We present the first results from a Hubble Space Telescope WFC3/IR program, which obtained direct imaging and grism observations of galaxies near quasar sightlines with a high frequency of uncorrelated foreground Mg II […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, Evan McDonough, , | Summary: We study gravitational particle production of the massive spin-$3/2$ Rarita-Schwinger field, and its close relative, the gravitino, in FRW cosmological spacetimes. For masses lighter than the value of the Hubble expansion rate after inflation, $m_{3/2} […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Hugh Garsden, Lincoln Greenhill, Gianni Bernardi, Anastasia Fialkov, Daniel C. Price | Summary: The Large-aperture Experiment to detect the Dark Age (LEDA) was designed to measure the 21-cm signal from neutral hydrogen at Cosmic Dawn, $z approx $15-30. Using observations made with the $approx $ 200 m […]
Kavli Affiliate: Katja C. Nowack | First 5 Authors: D. Low, G. M. Ferguson, Alexander Jarjour, Brian T. Schaefer, Maja D. Bachmann | Summary: We report a scanning superconducting quantum interference device (SQUID) microscope in a cryogen-free dilution refrigerator with a base temperature at the sample stage of at least 30 mK. The microscope is […]
Kavli Affiliate: Subo Dong | First 5 Authors: S. J. Brennan, M. Fraser, J. Johansson, A. Pastorello, R. Kotak | Summary: We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current literature by adding higher cadence as well as extended coverage […]
Kavli Affiliate: R. Morris | First 5 Authors: Cuc K. Dinh, Jesus M. Salas, Mark R. Morris, Smadar Naoz, | Summary: A Circumnuclear Disk (CND) of molecular gas occupies the central few parsecs of the Galactic Center. It is likely subject to turbulent disruptions from violent events in its surrounding environment, but the effect of […]
