An ALMA study of hub-filament systems I. On the clump mass concentration within the most massive cores
Michael Anderson, Nicolas Peretto, Sarah E. Ragan +7
The physical processes behind the transfer of mass from parsec-scale clumps to massive-star-forming cores remain elusive. We investigate the relation between the clump morphology a…
The Extended Distribution of Baryons Around Galaxies
Joel N. Bregman, Michael E. Anderson, Matthew J. Miller +5
We summarize and reanalyze observations bearing upon missing galactic baryons, where we propose a consistent picture for halo gas in L >~ L* galaxies. The hot X-ray emitting halos…
Baryon Budget of the Hot Circumgalactic Medium of Massive Spiral Galaxies
Jiang-Tao Li, Joel N. Bregman, Q. Daniel Wang +2
The baryon content around local galaxies is observed to be much less than is needed in Big Bang nucleosynthesis. Simulations indicate that a significant fraction of these "missing…
FUV line emission, gas kinematics, and discovery of [Fe XXI] 1354.1 in the sightline towards a filament in M87
Michael E. Anderson, Rashid Sunyaev
We present new HST-COS G130M spectroscopy for a sightline toward a filament projected 1.9 kpc from the nucleus of M87. The combination of the sensitivity of COS and the proximity o…
Increased Prevalence of Bent Lobes for Double-Lobed Radio Galaxies in Dense Environments
Ezekiel M. Silverstein, Michael E. Anderson, Joel N. Bregman
Double-lobed radio galaxies (DLRGs) often have radio lobes which subtend an angle of less than 180 degrees, and these bent DLRGs have been shown to associate preferentially with ga…
The Circum-Galactic Medium of MASsive Spirals II: Probing the Nature of Hot Gaseous Halo around the Most Massive Isolated Spiral Galaxies
Jiang-Tao Li, Joel N. Bregman, Q. Daniel Wang +3
We present the analysis of the XMM-Newton data of the Circum-Galactic Medium of MASsive Spirals (CGM-MASS) sample of six extremely massive spiral galaxies in the local Universe. Al…
The Circum-Galactic Medium of MASsive Spirals I: Overview and a Case Study of NGC 5908
Jiang-Tao Li, Joel N. Bregman, Q. Daniel Wang +2
The Circum-Galactic Medium of MASsive Spirals (CGM-MASS) is a project studying the overall content, physical and chemical properties, and spatial distributions of the multi-phase c…
A Deep XMM-Newton Study of the Hot Gaseous Halo Around NGC 1961
Michael E. Anderson, Eugene Churazov, Joel N. Bregman
We examine 11 XMM-Newton observations of the giant spiral galaxy NGC 1961, allowing us to study the hot gaseous halo of a spiral galaxy in unprecedented detail. We perform a spatia…
