Thermal Disk Winds in X-ray Binaries: Realistic Heating and Cooling Rates Give Rise to Slow, but Massive Outflows
Nick Higginbottom, Daniel Proga, Christian Knigge +1
A number of X-ray binaries exhibit clear evidence for the presence of disk winds in the high/soft state. A promising driving mechanism for these outflows is mass loss driven by the…
Observations of Lyman-alpha and O VI: Signatures of Cooling and Star Formation in a Massive Central Cluster Galaxy
Megan Donahue, Thomas Connor, G. Mark Voit +1
We report new HST COS and STIS spectroscopy of a star-forming region (~100 solar masses/year) in the center of the X-ray cluster RXJ1532.9+3021 (z=0.362), to follow-up the CLASH te…
Dissecting the Extended Main Sequence Turn-off of the Young Star Cluster NGC1850
Matteo Correnti, Paul Goudfrooij, Andrea Bellini +2
We use the Wide Field Camera 3 onboard the Hubble Space Telescope to obtain deep, high-resolution photometry of the young (~ 100 Myr) star cluster NGC1850 in the Large Magellanic C…
Multi-wavelength campaign on NGC7469 I. The rich 640 ks RGS spectrum
Ehud Behar, Uria Peretz, Gerard A. Kriss +15
Outflows in active galaxies (AGNs) are common, although their launching mechanism, location, and physical impact on the host galaxy remain controversial. We conducted a multiwavele…
New ATCA, ALMA and VISIR observations of the candidate LBV SK-67266 (S61): the nebular mass from modelling 3D density distributions
C. Agliozzo, R. Nikutta, G. Pignata +10
We present new observations of the nebula around the Magellanic candidate Luminous Blue Variable S61. These comprise high-resolution data acquired with the Australia Telescope Comp…
Fragmentation of Kozai-Lidov Disks
Wen Fu, Stephen H. Lubow, Rebecca G. Martin
We analyze the gravitational instability (GI) of a locally isothermal inclined disk around one component of a binary system. Such a disk can undergo global Kozai-Lidov (KL) cycles…
