Lensing-Reconstructed Dark Matter-Intracluster Medium Coherence as a Probe of Cluster Dynamical State: Application to HSTFF, RELICS, and CLASH Clusters
Giulia Cerini, Sayan Saha, Jacqueline McCleary +13
We present the first application of Fourier-space coherence analysis between the lensing-reconstructed projected mass distribution and the X-ray-emitting intracluster medium to a s…
Mapping dark matter in the Bullet Cluster using JWST imaging and spectroscopy
Gregor RihtarÅ¡iÄ, MaruÅ¡a BradaÄ, Guillaume Desprez +23
We present an updated gravitational lens model of the Bullet cluster (1E 0657-56) by combining JWST NIRCam imaging and NIRSpec spectroscopy. Although previous lens models relied on…
Warm, not Fuzzy: Generalized Ultralight Dark Matter Limits from Milky Way Satellites
Ethan O. Nadler, Mustafa A. Amin, Risa H. Wechsler +3
We generalize lower limits on the dark matter (DM) particle mass derived from Milky Way (MW) satellite galaxy abundances to scenarios in which DM is an ultralight scalar field…
Towards a measurement of the primordial helium isotope ratio
Ryan J. Cooke, James W. Johnson, Pasquier Noterdaeme +4
We report the discovery of two metastable neutral helium (He I*) absorbers in the Milky Way, and use the upgraded CRyogenic InfraRed Echelle Spectrograph on the Very Large Telescop…
