Lens Model Accuracy in the Expected LSST Lensed AGN Sample

Padma Venkatraman, S K Erickson, Philip J. Marshall, Martin Millon et autres

Abstract Strong gravitational lensing of active galactic nuclei (AGN) enables measurements of cosmological parameters through time-delay cosmography (TDC). With data from the upcoming LSST survey, we anticipate using a sample of O ( 1000 ) lensed AGN for TDC. To prepare for …

Design and Commissioning of a Deuterium-Tritium Gas Delivery System for Muon-Catalyzed Fusion in a Diamond Anvil Cell

Elena Koukina, Cody Fagan, Christopher Robert Shmayda, Jonathan D Kalow et autres

We report the design, commissioning, and operation of deuterium-deuterium (DD) and deuterium-tritium (DT) gas delivery systems developed to load a diamond anvil cell (DAC) beam target for muon-catalyzed fusion (µCF). The DAC approach enables DT fuel to be compressed to gigapascal pressures …

Euclid Quick Data Release (Q1) Euclid spectroscopy of quasars. 2. Physical properties from spectral fitting

Euclid Collaboration, J. Calhau, G. Calderone, A. Feltre et autres

A substantial volume of spectroscopic data has become available with the Euclid Data Release (Q1), which represents a unique opportunity to study quasars (QSOs) in the Euclid Deep Fields, provide spectroscopic measurements, and estimates of their physical properties. We present results from …

On the Impact of Correlated Noise and Spectral Resolution on the Retrieval Analysis of the Habitable World Observatory

Ji Wang, Philipp A. Huber, Sascha P. Quanz

Abstract Finding signs of life elsewhere in the universe is the holy grail of the field of exoplanets. Future space missions such as the Habitable World Observatory (HWO) are under development to search for biosignatures in exoplanets. We investigate the impact of …

One hundred years of spin: Fundamental physics, dark matter, exotic interactions, and all that

Dmitry Budker, T. E. Chupp, K. Kirch, W. Mike Snow

For a century, spin has been an indispensable probe of the fundamental laws of nature. A reflection on the role of spin in shaping modern physics is presented, from the early days of quantum mechanics to the latest precision tests of the …

Generation of a high-intensity, superthermal muonium beam for gravity and laser spectroscopy experiments

J. Zhang, Aldo Antognini, M. Bartkowiak, D. Goeldi et autres

Abstract The universality of free fall, a cornerstone of Einstein’s theory of gravity, has so far only been tested with neutral composite states of first-generation standard model particles, such as atoms, neutrons and antihydrogen. Muonium, the bound state of a positively charged …

JWST/MIRI Imaging Search for Kinematically Detected Protoplanetary Candidates

G. Cugno, M. Benisty, R. Teague, A. Boccaletti et autres

Kinematic perturbations observed with ALMA in CO line emission provide evidence for a population of embedded giant protoplanets shaping the structure of protoplanetary disks. We present JWST/MIRI F1140C ($λ= 11.3~μ$m) coronagraphic observations of five protoplanetary disks, HD163296, RXJ1615.3-3255, RXJ1842.9-3532, SY Cha, and …
