What You Don’t Know Can Hurt You: Use and Abuse of Astrophysical Models in Gravitational-wave Population Analyses

Kavli Affiliate: Salvatore Vitale | First 5 Authors: April Qiu Cheng, Michael Zevin, Salvatore Vitale, , | Summary: One of the goals of gravitational-wave astrophysics is to infer the number and properties of the formation channels of binary black holes (BBHs); to do so, one must be able to connect various models with the data. […]

The Postdoc Accord in Theoretical High Energy Physics

Kavli Affiliate: Lina Necib | First 5 Authors: Djuna Croon, Patrick J. Fox, Roni Harnik, Simon Knapen, Mariangela Lisanti | Summary: We present the results of a survey meant to assess the opinion of the high-energy physics theory (HET) community on the January 7th postdoc acceptance deadline – specifically, whether there is a preference to […]

Continuum Reverberation Mapping of Mrk 876 Over Three Years With Remote Robotic Observatories

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Jake A. Miller, Edward M. Cackett, Michael R. Goad, Keith Horne, Aaron J. Barth | Summary: Continuum reverberation mapping probes the sizescale of the optical continuum-emitting region in active galactic nuclei (AGN). Through 3 years of multiwavelength photometric monitoring in the optical with robotic observatories, we perform […]

BU Canis Minoris — the Most Compact Known Flat Doubly Eclipsing Quadruple System

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Theodor Pribulla, Tamás Borkovits, Rahul Jayaraman, Saul Rappaport, Tibor Mitnyan | Summary: We have found that the 2+2 quadruple star system BU CMi is currently the most compact quadruple system known, with an extremely short outer period of only 121 days. The previous record holder was TIC […]

X-ray metal line emission from the hot circumgalactic medium: probing the effects of supermassive black hole feedback

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nhut Truong, Annalisa Pillepich, Dylan Nelson, Ákos Bogdán, Gerrit Schellenberger | Summary: We derive predictions from state-of-the-art cosmological galaxy simulations for the spatial distribution of the hot circumgalactic medium (CGM, ${rm [0.1-1]R_{200c}}$) through its emission lines in the X-ray soft band ($[0.3-1.3]$ keV). In particular, we compare […]

EIGER IV: The cool 10$^4$K circumgalactic environment of high-$z$ galaxies reveals remarkably efficient IGM enrichment

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Rongmon Bordoloi, Robert A. Simcoe, Jorryt Matthee, Daichi Kashino, Ruari Mackenzie | Summary: We report new observations of the cool diffuse gas around 29, $2.3<z<6.3$ galaxies, using deep JWST/NIRCam slitless grism spectroscopy around the sightline to the quasar J0100+2802. The galaxies span a stellar mass range […]

Mapping the imprints of stellar and AGN feedback in the circumgalactic medium with X-ray microcalorimeters

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Gerrit Schellenberger, Ákos Bogdán, John A. ZuHone, Benjamin D. Oppenheimer, Nhut Truong | Summary: The Astro2020 Decadal Survey has identified the mapping of the circumgalactic medium (CGM, gaseous plasma around galaxies) as a key objective. We explore the prospects for characterizing the CGM in and around nearby […]
