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 weak gravitational lensing recalibration of the scaling relations linking the gas properties of dark halos to their mass
Wenting Wang, Simon White, Rachel Mandelbaum +3
We use weak gravitational lensing to measure mean mass profiles around Locally Brightest Galaxies (LBGs). These are selected from the SDSS/DR7 spectroscopic and photometric catalog…
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…
Searching for FUV line emission from K gas in massive elliptical galaxies and galaxy clusters as a tracer of turbulent velocities
Michael E. Anderson, Rashid Sunyaev
Non-thermal pressure from turbulence and bulk flows is a fundamental ingredient in hot gaseous halos, and in the intracluster medium it will be measured through emission line kinem…
Unifying X-ray Scaling Relations from Galaxies to Clusters
Michael E. Anderson, Massimo Gaspari, Simon D. M. White +2
We examine a sample of "locally brightest galaxies" selected from the Sloan Digital Sky Survey to be central galaxies within their dark matter halos. These were prev…
Non-Detection of X-Ray Emission From Sterile Neutrinos in Stacked Galaxy Spectra
Michael E. Anderson, Eugene Churazov, Joel N. Bregman
We conduct a comprehensive search for X-ray emission lines from sterile neutrino dark matter, motivated by recent claims of unidentified emission lines in the stacked X-ray spectra…
Modeling X-ray Emission Around Galaxies
Michael E. Anderson, Joel N. Bregman
Extended X-ray emission can be studied either spatially (through its surface brightness profile) or spectrally (by analyzing the spectrum at various locations in the field). Both t…
Extended Hot Halos Around Isolated Galaxies Observed in the ROSAT All-Sky Survey
Michael E. Anderson, Joel N. Bregman, Xinyu Dai
We place general constraints on the luminosity and mass of hot X-ray emitting gas residing in extended "hot halos" around nearby massive galaxies. We examine stacked images of 2165…
XMM-Newton Detects a Hot Gaseous Halo in the Fastest Rotating Spiral Galaxy UGC 12591
Xinyu Dai, Michael E. Anderson, Joel N. Bregman +1
We present our XMM-Newton observation of the fastest rotating spiral galaxy UGC 12591. We detect hot gas halo emission out to 110 kpc from the galaxy center, and constrain the halo…
Detection of a Hot Gaseous Halo Around the Giant Spiral Galaxy NGC 1961
Michael E. Anderson, Joel N. Bregman
Hot gaseous halos are predicted around all large galaxies and are critically important for our understanding of galaxy formation, but they have never been detected at distances bey…
Metal Production in Galaxy Clusters: The Non-Galactic Component
Joel N. Bregman, Michael E. Anderson, Xinyu Dai
The metallicity in galaxy clusters is expected to originate from the stars in galaxies, with a population dominated by high mass stars likely being the most important stellar compo…
Do Hot Haloes Around Galaxies Contain the Missing Baryons?
Michael E. Anderson, Joel N. Bregman
Galaxies are missing most of their baryons, and many models predict these baryons lie in a hot halo around galaxies. We establish observationally motivated constraints on the mass…
Redshift Evolution in the Iron Abundance of the Intracluster Medium
Michael E. Anderson, Joel N. Bregman, Suzanne C. Butler +1
Clusters of galaxies provide a closed box within which one can determine the chemical evolution of the gaseous baryons with cosmic time. We studied this metallicity evolution in th…
