Measuring weak microwave signals via current-biased Josephson Junctions II: Arriving at single-photon detection sensitivity
Y. Q. Chai, M. Y. Wang, S. N. Wang +2
It is well known that the current-biased Josephson junction (CBJJ) can serve as a Josephson threshold detector (JTD) for the sensitive detection of weak microwave signals. Based on…
Milky Way Satellite Census. IV. Constraints on Decaying Dark Matter from Observations of Milky Way Satellite Galaxies
S. Mau, E. O. Nadler, R. H. Wechsler +66
We use a recent census of the Milky Way (MW) satellite galaxy population to constrain the lifetime of particle dark matter (DM). We consider two-body decaying dark matter (DDM) in…
Nearest Neighbor: The Low-Mass Milky Way Satellite Tucana III
J. D. Simon, T. S. Li, A. Drlica-Wagner +56
We present Magellan/IMACS spectroscopy of the recently discovered Milky Way satellite Tucana III (Tuc III). We identify 26 member stars in Tuc III, from which we measure a mean rad…
Discovery of a Stellar Overdensity in Eridanus-Phoenix in the Dark Energy Survey
T. S. Li, E. Balbinot, N. Mondrik +56
We report the discovery of an excess of main sequence turn-off stars in the direction of the constellations of Eridanus and Phoenix from the first year data of the Dark Energy Surv…
