Lectures on 4d N=1 dynamics and related topics

Posted by dbos December 21, 2018Tokyo

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, , , , | Summary: This lecture series consists of mostly independent three parts: Part 1: a tour of basic 4d N=1 supersymmetric dynamics, covering the pure super Yang-Mills, the Seiberg duality for classical groups, the supersymmetric index on S^3, and the a-maximization. Part 2: […]

The ultra-diffuse galaxy NGC 1052-DF2 with MUSE: I. Kinematics of the stellar body

Posted by klaurent December 18, 2018Peking

Kavli Affiliate: Eric Peng | First 5 Authors: Eric Emsellem, Remco F. J. van der Burg, Jeremy Fensch, Tereza Jerabkova, Anita Zanella | Summary: The so-called ultra-diffuse galaxy NGC~1052-DF2 was announced to be a galaxy lacking dark matter based on a spectroscopic study of its constituent globular clusters. Here we present the first spectroscopic analysis […]

Ground motion prediction at gravitational wave observatories using archival seismic data

Posted by klaurent December 12, 2018MIT

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 […]

Candidate Massive Galaxies at $z sim 4$ in the Dark Energy Survey

Posted by klaurent November 29, 2018Stanford

Kavli Affiliate: Rafe Schindler | First 5 Authors: Pierandrea Guarnieri, Claudia Maraston, Daniel Thomas, Janine Pforr, Violeta Gonzalez-Perez | Summary: Using stellar population models, we predicted that the Dark Energy Survey (DES) – due to its special combination of area (5000 deg. sq.) and depth ($i = 24.3$) – would be in the position to […]

Astrometry and Occultation predictions to Trans-Neptunian and Centaur Objects observed within the Dark Energy Survey

Posted by November 26, 2018Chicago

Kavli Affiliate: Alex Drlica Wagner | First 5 Authors: Martin Banda-Huarca, Julio Camargo, Josselin Desmars, Ricardo Ogando, Roberto Vieira-Martins | Summary: Transneptunian objects (TNOs) are a source of invaluable information to access the history and evolution of the outer solar system. However, observing these faint objects is a difficult task. As a consequence, important properties […]

Magnifications of paired micro-images emerging from a micro-lensing critical curve

Posted by klaurent November 5, 2018MIT

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 […]
