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: 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 […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Ryuichiro Kitano, Ryutaro Matsudo, Norikazu Yamada, Masahito Yamazaki, | Summary: We propose a subvolume method to study the $theta$ dependence of the free energy density of the four-dimensional SU($N$) Yang-Mills theory on the lattice. As an attempt, the method is first applied to SU(2) Yang-Mills theory at […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Shun-ichi Horigome, Taisuke Katayose, Shigeki Matsumoto, Ipsita Saha, | Summary: The leptophilic weakly interacting massive particle (WIMP) is realized in a minimal renormalizable model scenario where scalar mediators with lepton number establish the WIMP interaction with the standard model (SM) leptons. We perform a comprehensive analysis for […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Richard Luhtaru, Paul L. Schechter, Kaylee M. de Soto, , | Summary: Among known strongly lensed quasar systems, ~25% have gravitational potentials sufficiently flat (and sources sufficiently well aligned) to produce four images rather than two. The projected flattening of the lensing galaxy and tides from […]
Kavli Affiliate: C. M. Ignarra | First 5 Authors: D. S. Akerib, S. Alsum, H. M. Araújo, X. Bai, J. Balajthy | Summary: We report here the results of an Effective Field Theory (EFT) WIMP search analysis using LUX data. We build upon previous LUX analyses by extending the search window to include nuclear recoil […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Charles P. Blakemore, Alexander Fieguth, Akio Kawasaki, Nadav Priel, Denzal Martin | Summary: We report on a search for non-Newtonian forces that couple to mass, with a characteristic scale of ${sim}10~mu$m, using an optically levitated microsphere as a precision force sensor. A silica microsphere trapped in an […]
