SPECTER: An Instrument Concept for CMB Spectral Distortion Measurements with Enhanced Sensitivity

Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Alina Sabyr, Carlos Sierra, J. Colin Hill, Jeffrey J. McMahon, | Summary: Deviations of the cosmic microwave background (CMB) energy spectrum from a perfect blackbody uniquely probe a wide range of physics, ranging from fundamental physics in the primordial Universe ($mu$-distortion) to late-time baryonic feedback processes […]

Symmetry-Based Structured Matrices for Efficient Approximately Equivariant Networks

Kavli Affiliate: Brian D. Nord | First 5 Authors: Ashwin Samudre, Mircea Petrache, Brian D. Nord, Shubhendu Trivedi, | Summary: There has been much recent interest in designing symmetry-aware neural networks (NNs) exhibiting relaxed equivariance. Such NNs aim to interpolate between being exactly equivariant and being fully flexible, affording consistent performance benefits. In a separate […]

Deciphering spatially resolved Lyman-alpha profiles in reionization analogs: the Sunburst Arc at cosmic noon

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Erik Solhaug, Hsiao-Wen Chen, Mandy C. Chen, Fakhri Zahedy, Max Gronke | Summary: The hydrogen Lyman-alpha (Lya) emission line, the brightest spectral feature of a photoionized gas, is considered an indirect tracer of the escape of Lyman continuum (LyC) photons, particularly when the intergalactic medium is […]

Map-level baryonification: Efficient modelling of higher-order correlations in the weak lensing and thermal Sunyaev-Zeldovich fields

Kavli Affiliate: Chihway Chang | First 5 Authors: Dhayaa Anbajagane, Shivam Pandey, Chihway Chang, , | Summary: Semi-analytic methods can generate baryon-corrected fields from N-body simulations (“baryonification”) and are rapidly becoming a ubiquitous tool in modeling structure formation on non-linear scales. We extend this formalism to consistently model the weak lensing and thermal Sunyaev-Zeldovich (tSZ) […]
