Kavli Affiliate: Risa Wechsler | Summary:The census of stellar streams and dwarf galaxies in the Milky Way provides direct constraints on galaxy formation models and the nature of dark matter. The DESI Milky Way survey — with a footprint of $14,000$ deg$^2$ and a depth of $r<19$ mag — delivers the largest sample of distant […]
Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:The ability to manipulate the surface states of topological insulators using electric or magnetic fields under ambient conditions is a key step toward their integration into future electronic and optoelectronic devices. Here, we demonstrate – using cyclotron resonance measurements on a tin-doped […]
Kavli Affiliate: Noah Kurinsky | Summary:A universal experimental challenge when studying radiation effects on cryogenic devices is to precisely and accurately characterize the position-dependent device response very near the energy detection threshold. We have developed a compact cryogenic optical beam steering system that can be used to generate O(μs) pulses of small numbers of photons […]
Kavli Affiliate: Roger D. Blandford | First 5 Authors: Adam D. Hincks, Adam D. Hincks, , , | Summary: Large sinusoidal variations in the radio light curves of the blazars PKS J0805$-$0111 and PKS 2131$-$021 have recently been discovered with an 18-year monitoring programme at the Owens Valley Radio Observatory, making these systems strong supermassive […]
Kavli Affiliate: Roger Blandford | Summary:Large sinusoidal variations in the radio light curves of the blazars PKS J0805$-$0111 and PKS 2131$-$021 have recently been discovered with an 18-year monitoring programme at the Owens Valley Radio Observatory, making these systems strong supermassive black hole binary (SMBHB) candidates. The sinusoidal variations in PKS 2131$-$021 dominate its light […]
Kavli Affiliate: Tom Abel | Summary:The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades. This concordance model is constructed by a universal cosmological constant and supported by a matter sector described by the standard model of particle physics […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Hongxing Chen, Snežana Stanimirović, Nickolas M. Pingel, James Dempsey, Frances Buckland-Willis | Summary: Cold neutral hydrogen (HI) is a crucial precursor for molecular gas formation and can be studied via HI absorption. This study investigates HI absorption in low column density regions of the Small and […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Andrew G. Sullivan, Roger W. Romani, , , | Summary: The intrabinary shocks (IBS) of spider pulsars emit non-thermal synchrotron X-rays from accelerated electrons and positrons in the shocked pulsar wind, likely energized by magnetic reconnection. In redback spider pulsars, the IBS typically wraps around the […]
Kavli Affiliate: Concetta Cartaro | Summary:Data preservation significantly increases the scientific output of high-energy physics experiments during and after data acquisition. For new and ongoing experiments, the careful consideration of long-term data preservation in the experimental design contributes to improving computational efficiency and strengthening the scientific activity in HEP through Open Science methodologies. This contribution […]
