Kavli Affiliate: Luis C. Ho | First 5 Authors: Boris S. Kalita, John D. Silverman, Emanuele Daddi, Connor Bottrell, Luis C. Ho | Summary: A key question in galaxy evolution has been the importance of the apparent `clumpiness’ of high redshift galaxies. Until now, this property has been primarily investigated in rest-frame UV, limiting our […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Eleonora Parlanti, Stefano Carniani, Hannah Übler, Giacomo Venturi, Francesco D’Eugenio | Summary: Dust-obscured galaxies are thought to represent an early evolutionary phase of massive galaxies in which the active galactic nucleus (AGN) is still deeply buried in significant amounts of dusty material and its emission is strongly […]

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Hsiao-Wen Chen, Zhijie Qu, Michael Rauch, Mandy C. Chen, Fakhri S. Zahedy | Summary: This paper reports the first measurement of the relationship between turbulent velocity and cloud size in the diffuse circumgalactic medium (CGM) in typical galaxy halos at redshift z~0.4-1. Through spectrally-resolved absorption profiles […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Hoang Nhan Luu, Philip Mocz, Mark Vogelsberger, Simon May, Josh Borrow | Summary: Dark matter as scalar particles consisting of multiple species is well motivated in string theory where axion fields are ubiquitous. A two-field fuzzy dark matter (FDM) model features two species of ultralight axion particles […]

Kavli Affiliate: Richard Kessler | First 5 Authors: Brodie Popovic, Daniel Scolnic, Maria Vincenzi, Mark Sullivan, Dillon Brout | Summary: Future constraints of cosmological parameters from Type Ia supernovae (SNe Ia) will depend on the use of photometric samples, those samples without spectroscopic measurements of the SNe Ia. There is a growing number of analyses […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Wendy L. Freedman, Barry F. Madore, , , | Summary: One of the most exciting and pressing issues in cosmology today is the discrepancy between some measurements of the local Hubble constant and other values of the expansion rate inferred from the cosmic microwave background (CMB) […]

Kavli Affiliate: Roger Blandford | First 5 Authors: Richard Anantua, Angelo Ricarte, George Wong, Razieh Emami, Roger Blandford | Summary: Horizon-scale observations of the jetted active galactic nucleus M87 are compared with simulations spanning a broad range of dissipation mechanisms and plasma content in three-dimensional general relativistic flows around spinning black holes. Observations of synchrotron […]
