The Cosmic Telescope that Lenses the Sunburst Arc, PSZ1 G311.65-18.48: Strong Gravitational Lensing model and Source Plane Analysis

Posted by klaurent Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keren Sharon, Guillaume Mahler, T. Emil Rivera-Thorsen, Hakon Dahle, Michael D. Gladders | Summary: We present a strong lensing analysis of the cluster PSZ1 G311.65-18.48, based on Hubble Space Telescope imaging, archival VLT/MUSE spectroscopy, and Chandra X-ray data. This cool-core cluster (z=0.443) lenses the brightest lensed […]

Stellar Bars in Isolated Gas-Rich Spiral Galaxies Do Not Slow Down

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Angus Beane, Lars Hernquist, Elena D’Onghia, Federico Marinacci, Charlie Conroy | Summary: Elongated bar-like features are ubiquitous in galaxies, occurring at the centers of approximately two-thirds of spiral disks. Due to gravitational interactions between the bar and the other components of galaxies, it is expected that angular […]

Opening the era of quasar host studies at high redshift with JWST

Posted by klaurent Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Xuheng Ding, John D. Silverman, Masafusa Onoue, , | Summary: We measure the host galaxy properties of five quasars with $zsim 1.6 – 3.5$ selected from SDSS and AEGIS, which fall within the JWST/HST CEERS survey area. A PSF library is constructed based on stars in […]

Quantum precision limits of displacement noise free interferometers

Posted by klaurent Caltech

Kavli Affiliate: Rana Adhikari | Summary:Current laser-interferometric gravitational wave detectors suffer from a fundamental limit to their precision due to the displacement noise of optical elements contributed by various sources. Several schemes for Displacement-Noise Free Interferometers (DFI) have been proposed to mitigate their effects. The idea behind these schemes is similar to decoherence-free subspaces in […]

Neutron stars as extreme laboratories for gravity tests

Posted by klaurent Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Lijing Shao, Kent Yagi, , , | Summary: Neutron stars are versatile in their application to studying various important aspects of fundamental physics, in particular strong-field gravity tests and the equation of state for super-dense nuclear matter at low temperatures. However, in many cases these two objectives […]
