Kavli Affiliate: Stuart L. Marshall | First 5 Authors: Mariko Kimura, Keisuke Isogai, Taichi Kato, Yoshihiro Ueda, Satoshi Nakahira | Summary: How black holes accrete surrounding matter is a fundamental, yet unsolved question in astrophysics. It is generally believed that matter is absorbed into black holes via accretion disks, the state of which depends primarily […]
Kavli Affiliate: Robert Byer | First 5 Authors: Shailendhar Saraf, Sasha Buchman, Karthik Balakrishnan, Chin Yang Lui, Michael Soulage | Summary: The UV LED mission demonstrates the precise control of the potential of electrically isolated test masses that is essential for the operation of space accelerometers and drag free sensors. Accelerometers and drag free sensors […]
Kavli Affiliate: Norbert Schulz | First 5 Authors: Jeroen Homan, Joseph Neilsen, Jessamyn L. Allen, Deepto Chakrabarty, Rob Fender | Summary: Recent work on jets and disk winds in low-mass X-ray binaries (LMXBs) suggests that they are to a large extent mutually exclusive, with jets observed in spectrally hard states and disk winds observed in […]
Kavli Affiliate: R. G. McMahon | First 5 Authors: Dale Mudd, Paul Martini, Suk Sien Tie, Chris Lidman, Richard McMahon | Summary: We present the discovery of a z=0.65 low-ionization broad absorption line (LoBAL) quasar in a post-starburst galaxy in data from the Dark Energy Survey (DES) and spectroscopy from the Australian Dark Energy Survey […]
Kavli Affiliate: Kunio Inoue | First 5 Authors: Ken-Ichi Fushimi, Hiroyasu Ejiri, Ryuta Hazama, Haruo Ikeda, Kunio Inoue | Summary: A high purity and large volume NaI(Tl) scintillator was developed to search for cosmic dark matter. The required densities of radioactive impurities (RIs) such as U-chain, Th-chain are less than a few ppt to establish […]
Kavli Affiliate: Juan I. Collar | First 5 Authors: Craig E. Aalseth, Juan I. Collar, Jim Colaresi, James E. Fast, Todd W. Hossbach | Summary: Recent progress on the development of very low noise high purity germanium ionization spectrometers has produced an instrument of 1.2 kg mass and excellent noise performance. The detector was installed […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Ofer Aharony, Yuji Tachikawa, Kiyonori Gomi, , | Summary: S-folds are generalizations of orientifolds in type IIB string theory, such that the geometric identifications are accompanied by non-trivial S-duality transformations. They were recently used by Garcia-Etxebarria and Regalado to provide the first construction of four dimensional N=3 […]

Kavli Affiliate: Edmund Bertschinger | First 5 Authors: Nina Abramzon, Patrice Benson, Edmund Bertschinger, Susan Blessing, Geraldine L. Cochran | Summary: Initiatives to increase the number, persistence, and success of women in physics in the US reach pre-teen girls through senior women. Programs exist at both the local and national levels. In addition, researchers have […]
Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: Consider the $3$-dimensional $mathcal N=4$ supersymmetric gauge theory associated with a compact Lie group $G_c$ and its quaternionic representation $mathbf M$. Physicists study its Coulomb branch, which is a noncompact hyper-K"ahler manifold with an $mathrm{SU}(2)$-action, possibly with singularities. […]
