Accurate method for ultralight axion CMB and matter power spectra

Kavli Affiliate: Wayne Hu | Summary:Ultralight axions (ULAs) with masses $10^-33 lesssim m/rm eV lesssim 10^-12$ are well motivated in string-inspired models and can be part or all of the dark energy or the dark matter in this range. Since the ULA field oscillates at a frequency $m$ that can be much larger than the […]

Pointing Accuracy Improvements for the South Pole Telescope with Machine Learning

Kavli Affiliate: John Carlstrom| First 5 Authors: P. M. Chichura, P. M. Chichura, , , | Summary:We present improvements to the pointing accuracy of the South Pole Telescope (SPT) using machine learning. The ability of the SPT to point accurately at the sky is limited by its structural imperfections, which are impacted by the extreme […]

Episodic super-Eddington accretion as a clue to Overmassive Black Holes in the early Universe

Kavli Affiliate: Roberto Maiolino | Summary:Early JWST observations are providing growing evidence for a ubiquitous population of accreting supermassive black holes (BHs) at high redshift, many of which appear overmassive compared to the empirically-derived local scaling relation between black hole mass and host galaxy stellar mass. In this study, we leverage predictions from the semi-analytical […]

Hidden in Pixels. I. Discovery of dual “little red dots” indicates excess clustering on kilo-parsec scales

Kavli Affiliate: Kohei Inayoshi | Summary:“Little Red Dots” (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST) and considered to be an early growth phase of supermassive black holes (SMBHs). Using a method of pixel-by-pixel color selection and relaxing the compactness criteria, we identify four dual LRD candidates in […]
