Stellar wind structures in the eclipsing binary system IGR J18027-2016
Federico A. Fogantini, Federico García, Jorge A. Combi +1
IGR J18027-2016 is an obscured high-mass X-ray binary formed by a neutron star accreting from the wind of a supergiant companion with a 4.57 day orbital period. The source sh…
A mag Super Flare of An Ultracool Star Detected by System
L. P. Xin, H. L. Li, J. Wang +21
In this paper, we report the detection and follow-ups of a super stellar flare GWAC\,181229A with an amplitude of 9.5 mag on a M9 type star by and the de…
Towards a physical understanding of the thermal background in large ground-based telescopes
Leonard Burtscher, Ioannis Politopoulos, Sergio Fernández-Acosta +11
Ground-based thermal-infrared observations have a unique scientific potential, but are also extremely challenging due to the need to accurately subtract the high thermal background…
Dust polarized emission observations of NGC 6334; BISTRO reveals the details of the complex but organized magnetic field structure of the high-mass star-forming hub-filament network
D. Arzoumanian, R. Furuya, T. Hasegawa +145
[Abridged] Filaments and hubs have received special attention recently thanks to studies showing their role in star formation. While the column density and velocity structures of b…
MusE GAs FLOw and Wind (MEGAFLOW) VII. A NOEMA pilot program to probe molecular gas in galaxies with measured circumgalactic gas flows
Jonathan Freundlich, Nicolas F. Bouché, Thierry Contini +5
We present a pilot program using IRAM's NOrthern Extended Millimeter Array (NOEMA) to probe the molecular gas reservoirs of six star-forming galaxies whose circumgalact…
First Co-spatial Comparison of Stellar, Neutral-, and Ionized-gas Metallicities in a metal-rich galaxy: M83
Svea Hernandez, Alessandra Aloisi, Bethan L. James +14
We carry out a comparative analysis of the metallicities from the stellar, neutral-gas, and ionized-gas components in the metal-rich spiral galaxy M83. We analyze spectroscopic obs…
