Compact near infrared sources in the center of the extraordinary galaxy IC 860
J. S. Gallagher, L. Schisgal, G. C. Privon +7
Hubble Space Telescope (HST) images are used to study the structure of the central regions of the luminous infrared galaxy (LIRG) IC 860. IC 860 is of special interest as a system…
Pressure-induced Superconductivity in AgSbTe2
Sudaice Kazibwe, Bishnu Karki, Wencheng Lu +8
AgSbTe2 is a well-known thermoelectric material with a high Seebeck coefficient and intrinsically low thermal conductivity, but its behavior under pressure remains largely unexplor…
A sub-ppm upper limit on the cosmological variations of the fine structure constant alpha
S. Muller, A. Beelen, M. Guelin +9
Absorption spectroscopy toward high-redshift quasars provides strong constraints on the putative variation of fundamental constants of physics on cosmological time scales. The subm…
Chemical complexity in star formation induced by stellar feedback: cores shock-formed by the supernova remnant W44
G. Cosentino, I. Jiménez-Serra, F. Fontani +8
Low-velocity shocks from Supernova Remnants (SNRs) may set the physical and chemical conditions of star formation in molecular clouds. Recent evidence suggests that the Sun might h…
Modeling of Dark Matter Prompt and Secondary Signatures in Dwarf Galaxies
Athithya Aravinthan, Julien Dörner, Julia Becker Tjus +6
Dwarf Spheroidal (dSph) galaxies are very promising laboratories for the indirect search for dark matter (DM), due to their low astrophysical background in radio and gamma-ray freq…
CO Depletion in Infrared Dark Clouds
G. Cosentino, J. C. Tan, C. Gainey +10
Infrared Dark Clouds (IRDCs) are cold, dense structures representative of the initial conditions of star formation. Many studies of IRDCs employ CO to investigate cloud dynamics. H…
