The generation and transformation of polarisation signals in molecular lines through collective anisotropic resonant scattering
Martin Houde, Boy Lankhaar, Fereshteh Rajabi +1
We discuss the existence of elliptical polarisation in rotational spectral lines of CO and other molecules within the context of the Anisotropic Resonant Scattering (ARS) model. We…
Bulk and Boundary Quantum Phase Transitions in a Square Rydberg Atom Array
Marcin Kalinowski, Rhine Samajdar, Roger G. Melko +3
Motivated by recent experimental realizations of exotic phases of matter on programmable quantum simulators, we carry out a comprehensive theoretical study of quantum phase transit…
The DES view of the Eridanus supervoid and the CMB Cold Spot
A. Kovács, N. Jeffrey, M. Gatti +119
The Cold Spot is a puzzling large-scale feature in the Cosmic Microwave Background temperature maps and its origin has been subject to active debate. As an important foreground str…
Strong-field Gravity Tests with the Double Pulsar
M. Kramer, I. H. Stairs, R. N. Manchester +27
Continued observations of the Double Pulsar, PSR J0737-3039A/B, consisting of two radio pulsars (A and B) that orbit each other with a period of 2.45hr in a mildly eccentric (e=0.0…
Orbit Tomography of Binary Supermassive Black Holes with Very Long Baseline Interferometry
Yun Fang, Huan Yang
In this work, we study how to infer the orbit of a supermassive black hole binary (SMBHB) by time-dependent measurements with Very Long Baseline Interferometry (VLBI), such as the…
The Atacama Cosmology Telescope: Measurement and Analysis of 1D Beams for DR4
Marius Lungu, Emilie R. Storer, Matthew Hasselfield +28
We describe the measurement and treatment of the telescope beams for the Atacama Cosmology Telescope's fourth data release, DR4. Observations of Uranus are used to measure the cent…
