Approximating Density Probability Distribution Functions Across Cosmologies

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Huanqing Chen, Nickolay Y. Gnedin, Philip Mansfield, , | Summary: Using a suite of self-similar cosmological simulations, we measure the probability distribution functions (PDFs) of real-space density, redshift-space density, and their geometric mean. We find that the real-space density PDF is well-described by a function of […]

The stellar mass versus stellar metallicity relation of star-forming galaxies at $1.6le zle3.0$ and implications for the evolution of the $α$-enhancement

Kavli Affiliate: John D. Silverman | First 5 Authors: Daichi Kashino, Simon J. Lilly, Alvio Renzini, Emanuele Daddi, Giovanni Zamorani | Summary: We measure the relationship between stellar mass and stellar metallicity, the stellar mass–metallicity relation (MZR), for 1336 star-forming galaxies at $1.6le zle3.0$ (<z>=2.2) using rest-frame far-ultraviolet spectra from the zCOSMOS-deep survey. High signal-to-noise […]

Searching for Axion-Like Particles from Core-Collapse Supernovae with Fermi LAT’s Low Energy Technique

Kavli Affiliate: Nicola Omodei | First 5 Authors: Milena Crnogorčević, Regina Caputo, Manuel Meyer, Nicola Omodei, Michael Gustafsson | Summary: Light axion-like particles (ALPs) are expected to be abundantly produced in core-collapse supernovae (CCSNe), resulting in a $sim$10-second long burst of ALPs. These particles subsequently undergo conversion into gamma-rays in external magnetic fields to produce […]

Evaluating and Enhancing Candidate Clocking Systems for CHIME/FRB VLBI Outriggers

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Savannah Cary, Juan Mena-Parra, Calvin Leung, Kiyoshi Masui, J. F. Kaczmarek | Summary: As the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has become the leading instrument for detecting Fast Radio Bursts (FRBs), CHIME/FRB Outriggers will use very-long-baseline interferometry (VLBI) to localize FRBs with milliarcsecond precision. The CHIME […]

Directional Detection of Light Dark Matter in Superconductors

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Yonit Hochberg, Eric David Kramer, Noah Kurinsky, Benjamin V. Lehmann, | Summary: Superconducting detectors have been proposed as outstanding targets for the direct detection of light dark matter scattering at masses as low as a keV. We study the prospects for directional detection of dark matter in […]

The Atacama Cosmology Telescope: Constraints on Pre-Recombination Early Dark Energy

Kavli Affiliate: David N. Spergel | First 5 Authors: J. Colin Hill, Erminia Calabrese, Simone Aiola, Nicholas Battaglia, Boris Bolliet | Summary: The early dark energy (EDE) scenario aims to increase the value of the Hubble constant ($H_0$) inferred from cosmic microwave background (CMB) data over that found in $Lambda$CDM, via the introduction of a […]

The obliquity of HIP 67522 b: a 17 Myr old transiting hot Jupiter-sized planet

Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Alexis Heitzmann, George Zhou, Samuel N. Quinn, Stephen C. Marsden, Duncan Wright | Summary: HIP 67522 b is a 17 Myr old, close-in ($P_{orb} = 6.96$ d), Jupiter-sized ($R = 10,R_{oplus}$) transiting planet orbiting a Sun like star in the Sco-Cen OB association. We present our […]

The effect of active galactic nuclei on the cold interstellar medium in distant star-forming galaxies

Kavli Affiliate: John D. Silverman | First 5 Authors: Francesco Valentino, Emanuele Daddi, Annagrazia Puglisi, Georgios E. Magdis, Vasily Kokorev | Summary: In the framework of a systematic ALMA study of IR-selected main-sequence and starburst galaxies at z~1-1.7 at typical ~1" resolution, we report on the effects of mid-IR- and X-ray-detected active galactic nuclei (AGN) […]
