Kavli Affiliate: Paul L. Schechter | First 5 Authors: Derek Baldwin, Paul L. Schechter, , , | Summary: Quasars are quadruply lensed only when they lie within the diamond caustic of a lensing galaxy. This precondition produces a Malmquist-like selection effect in observed populations of quadruply lensed quasars, overestimating the true caustic area. The bias […]

Kavli Affiliate: George Ricker | First 5 Authors: Michelle Kunimoto, Chelsea Huang, Evan Tey, Willie Fong, Katharine Hesse | Summary: We present a magnitude-limited set of lightcurves for stars observed over the TESS Extended Mission, as extracted from full-frame images (FFIs) by MIT’s Quick-Look Pipeline (QLP). QLP uses multi-aperture photometry to produce lightcurves for ~1 […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Yetli Rosas-Guevara, Silvia Bonoli, Massimo Dotti, David Izquierdo-Villalba, Alessandro Lupi | Summary: We use the magnetic-hydrodynamical simulation TNG50 to study the evolution of barred massive disc galaxies. Massive spiral galaxies are already present as early as $z=4$, and bar formation takes place already at those early times. […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Enrico Garaldi, Rahul Kannan, Aaron Smith, Volker Springel, Rüdiger Pakmor | Summary: The high-redshift intergalactic medium (IGM) and the primeval galaxy population are rapidly becoming the new frontier of extra-galactic astronomy. We investigate the IGM properties and their connection to galaxies at $zgeq5.5$ under different assumptions for […]

Kavli Affiliate: Nathan P. Lourie | First 5 Authors: Danielle Frostig, Sylvia Biscoveanu, Geoffrey Mo, Viraj Karambelkar, Tito Dal Canton | Summary: The Wide-Field Infrared Transient Explorer (WINTER) is a new 1 $text{deg}^2$ seeing-limited time-domain survey instrument designed for dedicated near-infrared follow-up of kilonovae from binary neutron star (BNS) and neutron star-black hole mergers. WINTER […]

Kavli Affiliate: Saul Rappaport | First 5 Authors: Brian P. Powell, Veselin Kostov, Saul Rappaport, Andrei Tokovinin, Avi Shporer | Summary: We report the discovery of a unique object of uncertain nature — but quite possibly a disintegrating asteroid or minor planet — orbiting one star of the widely separated binary TIC 400799224. We initially […]

Kavli Affiliate: Peter Fritschel | First 5 Authors: Varun Srivastava, Georgia Mansell, Camille Makarem, Minkyun Noh, Richard Abbott | Summary: The detectors of the laser interferometer gravitational-wave observatory (LIGO) are broadly limited by the quantum noise and rely on the injection of squeezed states of light to achieve their full sensitivity. Squeezing improvement is limited […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du, Andrew Benson, Stacy Kim | Summary: Self-interacting dark matter (SIDM) cosmologies admit an enormous diversity of dark matter (DM) halo density profiles, from low-density cores to high-density core-collapsed cusps. The possibility of the growth of high central density […]

Kavli Affiliate: Christopher Burke | First 5 Authors: Bryson Cale, Michael Reefe, Peter Plavchan, Angelle Tanner, Eric Gaidos | Summary: We present updated radial-velocity (RV) analyses of the AU Mic system. AU Mic is a young (22 Myr) early M dwarf known to host two transiting planets – $P_{b}sim8.46$ days, $R_{b}=4.38_{-0.18}^{+0.18} R_{oplus}$, $P_{c}sim18.86$ days, $R_{c}=3.51_{-0.16}^{+0.16} […]
