Kavli Affiliate: Rob Simcoe | First 5 Authors: Mansi M. Kasliwal, Scott Adams, Igor Andreoni, Michael Ashley, Nadia Blagorodnova | Summary: Opening up the dynamic infrared sky for systematic time-domain exploration would yield many scientific advances. Multi-messenger pursuits such as localizing gravitational waves from neutron star mergers and quantifying the nucleosynthetic yields require the infrared. […]
Kavli Affiliate: Jacqueline Hewitt | First 5 Authors: Adrian Liu, James Aguirre, Yacine Ali-Haimoud, Marcelo Alvarez, Adam Beardsley | Summary: In addition to being a probe of Cosmic Dawn and Epoch of Reionization astrophysics, the 21cm line at $z>6$ is also a powerful way to constrain cosmology. Its power derives from several unique capabilities. First, […]
Kavli Affiliate: Robert Goeke | First 5 Authors: Davide Gandolfi, Luca Fossati, John H. Livingston, Keivan G. Stassun, Sascha Grziwa | Summary: We report the discovery of a super-Earth and a sub-Neptune transiting the star HD 15337 (TOI-402, TIC 120896927), a bright (V=9) K1 dwarf observed by the Transiting Exoplanet Survey Satellite (TESS) in Sectors […]
Kavli Affiliate: Slawomir Gras | First 5 Authors: David Reitze, Rich Abbott, Carl Adams, Rana Adhikari, Nancy Aggarwal | Summary: Recent gravitational-wave observations from the LIGO and Virgo observatories have brought a sense of great excitement to scientists and citizens the world over. Since September 2015,10 binary black hole coalescences and one binary neutron star […]

Kavli Affiliate: Richard Mittleman | First 5 Authors: Nikhil Mukund, Michael Coughlin, Jan Harms, Sebastien Biscans, Jim Warner | Summary: Gravitational wave observatories have always been affected by tele-seismic earthquakes leading to a decrease in duty cycle and coincident observation time. In this analysis, we leverage the power of machine learning algorithms and archival seismic […]
Kavli Affiliate: Paul Schechter | First 5 Authors: Luke Weisenbach, Paul Schechter, Joachim Wambsganss, , | Summary: Studies of the inner regions of micro-lensed AGN during caustic crossing events have often relied upon the approximation that the magnification near a fold caustic is inversely proportional to the square root of the source-caustic distance. We examine […]
Kavli Affiliate: Maria T. Zuber | First 5 Authors: Christopher E. Carr, Noelle C. Bryan, Kendall N. Saboda, Srinivasa A. Bhattaru, Gary Ruvkun | Summary: Parabolic flights provide cost-effective, time-limited access to "weightless" or reduced gravity conditions experienced in space or on planetary surfaces, e.g. the Moon or Mars. These flights facilitate fundamental research – […]
Kavli Affiliate: Robert Simcoe | First 5 Authors: T. Emil Rivera-Thorsen, Håkon Dahle, Max Gronke, Matthew Bayliss, Jane Rigby | Summary: We present rest-frame ultraviolet and optical spectroscopy of the brightest lensed galaxy yet discovered, at redshift z = 2.4. This source reveals a characteristic, triple-peaked Lyman {alpha} profile which has been predicted by various […]
Kavli Affiliate: Edmund Bertschinger | First 5 Authors: David M. Hernandez, Edmund Bertschinger, , , | Summary: Calculating the long term solution of ordinary differential equations, such as those of the $N$-body problem, is central to understanding a wide range of dynamics in astrophysics, from galaxy formation to planetary chaos. Because generally no analytic solution […]
