Measuring $H_0$ using X-ray and SZ effect observations of dynamically relaxed galaxy clusters

Kavli Affiliate: Adam B. Mantz | First 5 Authors: Jenny T. Wan, Adam B. Mantz, Jack Sayers, Steven W. Allen, R. Glenn Morris | Summary: We use a sample of 14 massive, dynamically relaxed galaxy clusters to constrain the Hubble Constant, $H_0$, by combining X-ray and Sunyaev-Zel’dovich (SZ) effect signals measured with Chandra, Planck and […]

First Star Formation in the Presence of Primordial Magnetic Fields

Kavli Affiliate: Tom Abel | First 5 Authors: Daegene Koh, Tom Abel, Karsten Jedamzik, , | Summary: It has been recently claimed that primordial magnetic fields could relieve the cosmological Hubble tension. We consider the impact of such fields on the formation of the first cosmological objects, mini-halos forming stars, for present-day field strengths in […]

Optical coherence and energy-level properties of a Tm$^{3+}$-doped LiNbO$_{3}$ waveguide at sub-Kelvin temperatures

Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Neil Sinclair, Daniel Oblak, Erhan Saglamyurek, Rufus L. Cone, Charles W. Thiel | Summary: We characterize the optical coherence and energy-level properties of the 795 nm $^3$H$_6$ to $^3$H$_4$ transition of Tm$^{3+}$ in a Ti$^{4+}$:LiNbO$_{3}$ waveguide at temperatures as low as 0.65 K. Coherence properties are measured […]

Floquet chiral hinge modes and their interplay with Weyl physics in a three-dimensional lattice

Kavli Affiliate: Biao Huang | First 5 Authors: Biao Huang, Viktor Novičenko, André Eckardt, Gediminas Juzeliūnas, | Summary: We demonstrate that a three dimensional time-periodically driven (Floquet) lattice can exhibit chiral hinge states and describe their interplay with Weyl physics. A peculiar type of the hinge states are enforced by the repeated boundary reflections with […]

Determining Dark Matter-Electron Scattering Rates from the Dielectric Function

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Yonit Hochberg, Yonatan Kahn, Noah Kurinsky, Benjamin V. Lehmann, To Chin Yu | Summary: We show that the rate for dark matter-electron scattering in an arbitrary material is determined by an experimentally measurable quantity, the complex dielectric function, for any dark matter interaction that couples to electron […]

Dark Matter Constraints from a Unified Analysis of Strong Gravitational Lenses and Milky Way Satellite Galaxies

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Simon Birrer, Daniel Gilman, Risa H. Wechsler, Xiaolong Du | Summary: Joint analyses of small-scale cosmological structure probes are relatively unexplored and promise to advance measurements of microphysical dark matter properties using heterogeneous data. Here, we present a multidimensional analysis of dark matter […]

CO excitation, molecular gas density and interstellar radiation field in local and high-redshift galaxies

Kavli Affiliate: John Silverman | First 5 Authors: Daizhong Liu, Emanuele Daddi, Eva Schinnerer, Toshiki Saito, Adam Leroy | Summary: We study the Carbon Monoxide (CO) excitation, mean molecular gas density and interstellar radiation field (ISRF) intensity in a comprehensive sample of 76 galaxies from local to high redshift (z~0-6), selected based on detections of […]
