Reconstructing the early-universe expansion and thermal history
Rui An, Vera Gluscevic
We present a model-independent reconstruction of the early expansion and thermal histories of the universe, obtained from light element abundance measurements. The expansion histor…
Search for high-energy neutrinos from magnetars with IceCube
Ava Ghadimi, Marcos Santander
Neutron stars with very strong magnetic fields are known as magnetars. There are multiple theories that predict magnetars may be able to emit high-energy (HE) neutrinos through had…
The Atacama Cosmology Telescope: High-resolution component-separated maps across one-third of the sky
William R. Coulton, Mathew S. Madhavacheril, Adriaan J. Duivenvoorden +151
Observations of the millimeter sky contain valuable information on a number of signals, including the blackbody cosmic microwave background (CMB), Galactic emissions, and the Compt…
The Atacama Cosmology Telescope: Mitigating the impact of extragalactic foregrounds for the DR6 CMB lensing analysis
Niall MacCrann, Blake D. Sherwin, Frank J. Qu +47
We investigate the impact and mitigation of extragalactic foregrounds for the CMB lensing power spectrum analysis of Atacama Cosmology Telescope (ACT) data release 6 (DR6) data. Tw…
The Atacama Cosmology Telescope: DR6 Gravitational Lensing Map and Cosmological Parameters
Mathew S. Madhavacheril, Frank J. Qu, Blake D. Sherwin +156
We present cosmological constraints from a gravitational lensing mass map covering 9400 sq. deg. reconstructed from CMB measurements made by the Atacama Cosmology Telescope (ACT) f…
The Atacama Cosmology Telescope: A Measurement of the DR6 CMB Lensing Power Spectrum and its Implications for Structure Growth
Frank J. Qu, Blake D. Sherwin, Mathew S. Madhavacheril +155
We present new measurements of cosmic microwave background (CMB) lensing over sq. deg. of the sky. These lensing measurements are derived from the Atacama Cosmology Telescop…
The Atacama Cosmology Telescope: Systematic Transient Search of 3-Day Maps
Yaqiong Li, Emily Biermann, Sigurd Naess +34
We conduct a systematic search for transients in three years of data (2017-2019) from the Atacama Cosmology Telescope (ACT). ACT covers 40 percent of the sky at three bands spannin…
Can Neutrino Self-interactions Save Sterile Neutrino Dark Matter?
Rui An, Vera Gluscevic, Ethan O. Nadler +1
Sterile neutrinos only interact with the Standard Model through the neutrino sector, and thus represent a simple dark matter (DM) candidate with many potential astrophysical and co…
Tension in the Context of Dark Matter-Baryon Scattering
Adam He, Mikhail M. Ivanov, Rui An +1
We explore an interacting dark matter (IDM) model that allows for a fraction of dark matter (DM) to undergo velocity-independent scattering with baryons. In this scenario, structur…
Structure Formation and the Global 21-cm Signal in the Presence of Coulomb-like Dark Matter-Baryon Interactions
Trey Driskell, Ethan O. Nadler, Jordan Mirocha +6
Many compelling dark matter (DM) scenarios feature Coulomb-like interactions between DM particles and baryons, in which the cross section for elastic scattering scales with relativ…
The Atacama Cosmology Telescope: limits on dark matter-baryon interactions from DR4 power spectra
Zack Li, Rui An, Vera Gluscevic +20
Diverse astrophysical observations suggest the existence of cold dark matter that interacts only gravitationally with radiation and ordinary baryonic matter. Any nonzero coupling b…
The Atacama Cosmology Telescope: The Persistence of Neutrino Self-Interaction in Cosmological Measurements
Christina D. Kreisch, Minsu Park, Erminia Calabrese +21
We use data from the Atacama Cosmology Telescope (ACT) DR4 to search for the presence of neutrino self-interaction in the cosmic microwave background. Consistent with prior works,…
Dark Matter Physics from the CMB-S4 Experiment
Cora Dvorkin, Renée Hlozek, Rui An +10
The nature of dark matter is one of the major puzzles of fundamental physics, integral to the understanding of our universe across almost every epoch. The search for dark matter ta…
Design and performance of the multi-PMT optical module for IceCube Upgrade
T. Anderson, L. Classen, A. T. Fienberg +5
The IceCube Upgrade is the first step towards the next-generation neutrino observatory at the South Pole, IceCube-Gen2, and will be installed in the central region of the existing…
A next-generation optical sensor for IceCube-Gen2
Vedant Basu, Aya Ishihara, Markus Dittmer +1
For the in-ice component of the next generation neutrino observatory at the South Pole, IceCube-Gen2, a new sensor module is being developed, which is an evolution of the D-Egg and…
Direction Reconstruction using a CNN for GeV-Scale Neutrinos in IceCube
Shiqi Yu
The IceCube Neutrino Observatory observes neutrinos interacting deep within the South Pole ice. It consists of 5,160 digital optical modules embedded within a cubic kilometer of ic…
