We present the decadal brightening of non-thermal emission flux in the northeastern filament of the young supernova remnant Cassiopeia A (Cas A), which highlights dynamic processes…
Arcsecond-Scale X-ray Imaging and Spectroscopy of SS 433 with Chandra HETG
Yusuke Sakai, Shinya Yamada, Haruka Sakemi +5
We present a spatial and spectral analysis of arcsecond-scale X-ray emission in SS 433 using zeroth-order data from Chandra High-Energy Transmission Grating (HETG) observations. Th…
Unified Gas Heating Constraints on Extended Dark Matter Compact Objects
TaeHun Kim, Philip Lu, Volodymyr Takhistov
We present the first unified constraints on a broad class of extended dark matter compact objects (EDCOs) from interstellar gas heating. These include axion stars, Q-balls, axion m…
On the computational feasibility of Bayesian end-to-end analysis of LiteBIRD simulations within Cosmoglobe
R. Aurvik, M. Galloway, E. Gjerløw +107
We assess the computational feasibility of end-to-end Bayesian analysis of the JAXA-led LiteBIRD experiment by analysing simulated time ordered data (TOD) for a subset of detectors…
A Simulation Framework for the LiteBIRD Instruments
M. Tomasi, L. Pagano, A. Anand +111
LiteBIRD, the Lite (Light) satellite for the study of -mode polarization and Inflation from cosmic background Radiation Detection, is a space mission focused on primordial cosmo…
Requirements on bandpass resolution and measurement precision for LiteBIRD
S. Giardiello, A. Carones, T. Ghigna +95
In this work, we study the impact of an imperfect knowledge of the instrument bandpasses on the estimate of the tensor-to-scalar ratio in the context of the next-generation Lit…
First Limits on Light Dark Matter Interactions in a Low Threshold Two Channel Athermal Phonon Detector from the TESSERACT Collaboration
C. L. Chang, Y. -Y. Chang, L. Chaplinsky +45
We present results of a search for spin-independent dark matter-nucleon interactions in a 1 cm by 1 mm thick (0.233 gram) high-resolution silicon athermal phonon detector opera…
Multimessenger Astronomy Beyond the Standard Model: New Window from Quantum Sensors
Jason Arakawa, Muhammad H. Zaheer, Volodymyr Takhistov +3
Ultralight bosonic (ULB) fields with mass ~eV often arise in theories beyond the Standard Model (SM). If such fields exist, violent astrophysical events that result in e…
Primordial Black Hole Formation from Power Spectrum with Finite-width
Shi Pi, Misao Sasaki, Volodymyr Takhistov +1
Primordial black holes (PBHs) can form from gravitational collapse of large overdensities in the early Universe, giving rise to rich phenomena in astrophysics and cosmology. We dev…
Potential Surge Preheating: enhanced resonance from potential features
Pankaj Saha, Yuko Urakawa
We investigate the effects of local features in the inflationary potential on the preheating dynamics after inflation. We show that a small feature in the potential can enhance the…
Low Energy Backgrounds and Excess Noise in a Two-Channel Low-Threshold Calorimeter
Robin Anthony-Petersen, Clarence L. Chang, Yen-Yung Chang +29
We describe observations of low energy excess (LEE) events, background events observed in all light dark matter direct detection calorimeters, and noise in a Transition Edge Sensor…
Polarized X-rays Correlated with Short--Timescale Variability of Cygnus X-1
Kaito Ninoyu, Yuusuke Uchida, Shinya Yamada +4
We systematically investigate the variability of polarized X-rays on a timescale of a few seconds in the low/hard state of the black hole binary Cygnus X-1. The correlation between…
Multi-dimensional optimisation of the scanning strategy for the LiteBIRD space mission
Y. Takase, L. Vacher, H. Ishino +105
Large angular scale surveys in the absence of atmosphere are essential for measuring the primordial -mode power spectrum of the Cosmic Microwave Background (CMB). Since this pro…
