Kavli Affiliate: Bruce Macintosh | Summary:HD~143811~AB is the host star to the directly imaged planet HD~143811~AB~b, which was recently discovered using data from the Gemini Planet Imager and Keck NIRC2. A member of the Sco-Cen star-forming region with an age of $13 pm 4$ Myr, HD~143811~AB is somewhat rare among hosts of directly imaged planets […]
Kavli Affiliate: Brian Lantz| First 5 Authors: Giulio Avoni, Giulio Avoni, , , | Summary:Experimental studies of ultra-relativistic heavy ion collisions at the Large Hadron Collider (LHC) depend crucially on Zero Degree Calorimeters (ZDCs) that measure neutrons produced at near-beam rapidity in nucleus-nucleus collisions. In hadronic nuclear collisions these neutrons are mainly spectator neutrons, those […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Michael Zhang, Michael Zhang, , , | Summary: A handful of enigmatic Jupiter-mass objects have been discovered orbiting pulsars. One such object, PSR J2322-2650b, uniquely resembles a hot Jupiter exoplanet due to its minimum density of 1.8 g/cm^3 and its ~1900 K equilibrium temperature. We use […]

One such object, PSR,J2322-2650b, uniquely resembles a hot Jupiter exoplanet due to its minimum density of 1.8 g/cm^3 and its ~1900 K equilibrium temperature. We use JWST to observe PSR J2322-2650b’s emission spectrum across an entire orbit. In stark […]
Kavli Affiliate: D. B. Macfarlane | Summary:We present constraints on low mass dark matter-electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken underground in the NEXUS facility located at Fermilab with an overburden of 225 meters of water equivalent. The experiment benefits from the minimizing of luminescence from the […]

Kavli Affiliate: Giorgio Gratta | Summary:Mechanical modulation of recoilless nuclear transitions allows the dynamic control of γ-ray emission and absorption. Accessing modulation frequencies well above the nuclear linewidth enables coherent manipulation of the nuclear response. Here we demonstrate such control by coupling a film of enriched 57Fe to a 97.9 MHz surface acoustic wave, which […]
Kavli Affiliate: Giorgio Gratta | Summary:Mechanical modulation of recoilless nuclear transitions allows the dynamic control of $γ$-ray emission and absorption. Accessing modulation frequencies well above the nuclear linewidth enables coherent manipulation of the nuclear response. Here we demonstrate high frequency control via efficient coupling a film of enriched $^57$Fe to a $97.9~mathrmMHz$ surface acoustic wave, […]
Kavli Affiliate: Risa Wechsler | Summary:This community paper developed out of the NSF Workshop on the Future of Artificial Intelligence (AI) and the Mathematical and Physics Sciences (MPS), which was held in March 2025 with the goal of understanding how the MPS domains (Astronomy, Chemistry, Materials Research, Mathematical Sciences, and Physics) can best capitalize on, […]
