Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Anna V. Payne, Benjamin J. Shappee, Jason T. Hinkle, Patrick J. Vallely, Christopher S. Kochanek | Summary: We present the discovery that ASASSN-14ko is a periodically flaring AGN at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky Automated […]
Kavli Affiliate: Lina Necib | First 5 Authors: Laura J. Chang, Lina Necib, , , | Summary: The distribution of dark matter in dwarf galaxies can have important implications on our understanding of galaxy formation as well as the particle physics properties of dark matter. However, accurately characterizing the dark matter content of dwarf galaxies […]
Kavli Affiliate: Edward Morgan | First 5 Authors: Fei Dai, Arpita Roy, Benjamin Fulton, Paul Robertson, Lea Hirsch | Summary: We report the measurement of a spectroscopic transit of TOI-1726 c, one of two planets transiting a G-type star with $V$ = 6.9 in the Ursa Major Moving Group ($sim$400 Myr). With a precise age […]
Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Calvin Leung, Juan Mena-Parra, Kiyoshi Masui, Mohit Bhardwaj, P. J. Boyle | Summary: We demonstrate the blind interferometric detection and localization of two fast radio bursts (FRBs) with 2- and 25-arcsecond precision on the 400-m baseline between the Canadian Hydrogen Intensity Mapping Experiment (CHIME) and the CHIME […]
Kavli Affiliate: Saul Rappaport | First 5 Authors: Maximilian N. Günther, David A. Berardo, Elsa Ducrot, Catriona A. Murray, Keivan G. Stassun | Summary: New sets of young M dwarfs with complex, sharp-peaked, and strictly periodic photometric modulations have recently been discovered with Kepler/K2 and TESS data. All of these targets are part of young […]
Kavli Affiliate: Lee McCuller | First 5 Authors: Kentaro Komori, Dhruva Ganapathy, Chris Whittle, Lee McCuller, Lisa Barsotti | Summary: Quantum vacuum fluctuations fundamentally limit the precision of optical measurements, such as those in gravitational-wave detectors. Injection of conventional squeezed vacuum can be used to reduce quantum noise in the readout quadrature, but this reduction […]
Kavli Affiliate: Lisa Barsotti | First 5 Authors: Chris Whittle, Kentaro Komori, Dhruva Ganapathy, Lee McCuller, Lisa Barsotti | Summary: Vacuum quantum fluctuations impose a fundamental limit on the sensitivity of gravitational-wave interferometers, which rank among the most sensitive precision measurement devices ever built. The injection of conventional squeezed vacuum reduces quantum noise in one […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Alvin J. K. Chua, Michael L. Katz, Niels Warburton, Scott A. Hughes, | Summary: The future space mission LISA will observe a wealth of gravitational-wave sources at millihertz frequencies. Of these, the extreme-mass-ratio inspirals of compact objects into massive black holes are the only sources that […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, , , | Summary: We analyze in full-detail the geometric structure of the covariant phase space (CPS) of any local field theory defined over a space-time with boundary. To this end, we introduce a new frame: the "relative bicomplex framework". […]
Kavli Affiliate: Moritz Guenther | First 5 Authors: Michihiro Takami, Tracy L. Beck, P. Christian Schneider, Hans Moritz Guenther, Marc White | Summary: For the active T-Taur star RW Aur A we have performed long-term (~10 yr) monitoring observations of (1) jet imaging in the [Fe II] 1.644-micron emission line using Gemini-NIFS and VLT-SINFONI; (2) […]
