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 […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, SuperCDMS Collaboration, , , | 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 […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Albert Nazeeri, Albert Nazeeri, , , | Summary: Mechanical modulation of recoilless nuclear transitions allows the dynamic control of gamma-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 […]
Kavli Affiliate: Risa Wechsler | First 5 Authors: Andrew Ferguson, Andrew Ferguson, , , | 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, […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Diego Maglione, Diego Maglione, , , | Summary: Magnetic fields are a fundamental part of the interstellar medium (ISM) and remain a challenge for building a comprehensive understanding of galactic properties. Their study requires far-infrared polarimetric observations, which provide an unrivaled probe of the dynamics, magnetization, […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Peter W. Graham, , , | Summary: Recent observations of the cosmic microwave background (CMB) and baryon acoustic oscillations (BAO) show some tension with a $Lambda$CDM cosmology. For one, the cosmological parameters determined by the CMB are at odds with the expansion history […]
Kavli Affiliate: Troy A. Porter | First 5 Authors: Shmuel Bialy, Shmuel Bialy, , , | Summary: Stars and planets form within cold, dark molecular clouds. In these dense regions, where starlight cannot penetrate, cosmic rays (CRs) are the dominant source of ionization — driving interstellar chemistry(Dalgarno (2006, PNAS, 103, 12269)), setting the gas temperature(Goldsmith […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: M. F. Albakry, M. F. Albakry, , , | Summary: SuperCDMS SNOLAB uses kilogram-scale germanium and silicon detectors to search for dark matter. Each detector has Transition Edge Sensors (TESs) patterned on the top and bottom faces of a large crystal substrate, with the TESs electrically […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Aditya R. Sengupta, Aditya R. Sengupta, , , | Summary: Photonic lanterns (PLs) are fiber-based waveguides that are capable of focal-plane wavefront sensing while simultaneously directing light to downstream science instruments. The optimal choice of wavefront reconstruction algorithm has yet to be determined, and likely depends on […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Marta Nowotka, Marta Nowotka, , , | Summary: We present a joint analysis of HI absorption Zeeman measurements and the morphology of filamentary HI emission to investigate the three-dimensional structure of the magnetic field in the diffuse neutral interstellar medium (ISM). Our analysis is based on […]
