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…
