HD 21520 b: a warm sub-Neptune transiting a bright G dwarf

Kavli Affiliate: Avi Shporer | First 5 Authors: Molly Nies, Ismael Mireles, François Bouchy, Diana Dragomir, Belinda A. Nicholson | Summary: We report the discovery and validation of HD 21520 b, a transiting planet found with TESS and orbiting a bright G dwarf (V=9.2, $T_{eff} = 5871 pm 62$ K, $R_{star} = 1.04pm 0.02, R_{odot}$). […]

Constraints on Ultra Heavy Dark Matter Properties from Dwarf Spheroidal Galaxies with LHAASO Observations

Kavli Affiliate: Li Xin Li | First 5 Authors: Zhen Cao, F. Aharonian, Q. An, Axikegu, Y. X. Bai | Summary: In this work we try to search for signals generated by ultra-heavy dark matter at the Large High Altitude Air Shower Observatory (LHAASO) data. We look for possible gamma-ray by dark matter annihilation or […]

The SDSS-V Black Hole Mapper Reverberation Mapping Project: CIV BAL Acceleration in the Quasar SBS 1408+544

Kavli Affiliate: Claudio Ricci | First 5 Authors: Robert Wheatley, Catherine J. Grier, Patrick B. Hall, W. N. Brandt, Jonah Lotz | Summary: We present the results of an investigation of a highly variable CIV broad absorption-line feature in the quasar SBS 1408+544 (z=2.337) that shows a significant shift in velocity over time. This source […]

Warm Hawking Relics From Primordial Black Hole Domination

Kavli Affiliate: Gordan Z. Krnjaic | First 5 Authors: Christopher J. Shallue, Julian B. Muñoz, Gordan Z. Krnjaic, , | Summary: We study the cosmological impact of warm, dark-sector relic particles produced as Hawking radiation in a primordial-black-hole-dominated universe before big bang nucleosynthesis. If those dark-sector particles are stable, they would survive to the present […]

The Size-luminosity Relation of the AGN Torus Determined from the Comparison between Optical and Mid-infrared Variability

Kavli Affiliate: Luis C. Ho | First 5 Authors: Minjin Kim, Suyeon Son, Luis C. Ho, , | Summary: We investigate the optical variability of low-redshift ($0.15< zleq0.4$) active galactic nuclei using the multi-epoch data from the Zwicky Transient Facility. We find that a damped random walk model well describes the ensemble structure function in […]
