All the Little Things in Abell 2744: $>$1000 Gravitationally Lensed Dwarf Galaxies at $z=0-9$ from JWST NIRCam Grism Spectroscopy

Posted by dbos October 2, 2024MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Rohan P. Naidu, Jorryt Matthee, Ivan Kramarenko, Andrea Weibel, Gabriel Brammer | Summary: Dwarf galaxies hold the key to crucial frontiers of astrophysics, however, their faintness renders spectroscopy challenging. Here we present the JWST Cycle 2 survey, All the Little Things (ALT, PID 3516), which is […]

A Catalog of Pulsar X-ray Filaments

Posted by dbos October 2, 2024October 14, 2024Stanford

Kavli Affiliate: Roger W. Romani | First 5 Authors: Jack T. Dinsmore, Roger W. Romani, , , | Summary: We present the first Chandra X-ray Observatory (CXO) catalog of "pulsar X-ray filaments," or "misaligned outflows." These are linear, synchrotron radiating features powered by ultra-relativistic electrons and positrons that escape from bow shock pulsars. The filaments […]

TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days

Posted by dbos October 2, 2024October 14, 2024MIT

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Veselin B. Kostov, Saul A. Rappaport, Tamas Borkovits, Brian P. Powell, Robert Gagliano | Summary: We have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, Pout, of only 24.5 days. This "eclipses" the previous record set by lambda Tauri at […]
