Kavli Affiliate: Luis C. Ho | First 5 Authors: Vivek Kumar Jha, Ravi Joshi, Hum Chand, Xue-Bing Wu, Luis C. Ho | Summary: We present the accretion disk size estimates for a sample of 19 active galactic nuclei (AGN) using the optical $g$, $r$, and $i$ band light curves obtained from the Zwicky Transient Facility […]
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 […]
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 […]
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 […]
Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Emily A. Gilbert, Thomas Barclay, Elisa V. Quintana, Lucianne M. Walkowicz, Laura D. Vega | Summary: AU Mic is a young ($sim$24 Myr), pre-Main Sequence M~dwarf star that was observed in the first month of science observations of the Transiting Exoplanet Survey Satellite (TESS) and re-observed […]
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) […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Sultan Hassan, Romeel Davé, Matthew McQuinn, Rachel S. Somerville, Laura C. Keating | Summary: Traditional large-scale models of reionization usually employ simple deterministic relations between halo mass and luminosity to predict how reionization proceeds. We here examine the impact on modelling reionization of using more detailed […]
Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Daniel Harlow, Hirosi Ooguri, , , | Summary: In this paper we use Euclidean gravity to derive a simple formula for the density of black hole microstates which transform in each irreducible representation of any finite gauge group. Since each representation appears with nonzero density, this gives […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Joris Witstok, Renske Smit, Roberto Maiolino, Mirko Curti, Nicolas Laporte | Summary: We present a detailed spectroscopic analysis of a galaxy at $z simeq 4.88$ that is, by chance, magnified $sim 30 times$ by gravitational lensing. Only three sources at $z gtrsim 5$ are known with such […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Thomas Siegert, Roland M. Crocker, Oscar Macias, Fiona H. Panther, Francesca Calore | Summary: We use 15 years of $gamma$-ray data from INTEGRAL/SPI in a refined investigation of the morphology of the Galactic bulge positron annihilation signal. Our spatial analysis confirms that the signal traces the old […]
