We present a 60 ks Chandra ACIS-S observation of the isolated edge-on spiral galaxy NGC 3556, together with a multiwavelength analysis of various discrete X-ray sources and diffuse X-ray features. Among 33 discrete X-ray sources detected within the IB = 25 mag arcsec-2 isophote ellipse of the galaxy, we identify a candidate for the galactic nucleus, an ultraluminous X-ray source that might be an accreting intermediate-mass black hole, a possible X-ray binary with a radio counterpart, and two… 

Erratum: Chandra observation of the edge-on spiral NGC 5775: probing the hot galactic disc/halo connection

We study the edge-on galaxy NGC 5775, utilizing a 58.2 ks Chandra ACIS-S observation together with complementary Hubble Space Telescope (HST) ACS, Spitzer IRAC and other multi-wavelength data sets.

Chandra and XMM–Newton detection of large-scale diffuse X-ray emission from the Sombrero galaxy

We present an X-ray study of the massive edge-on Sa galaxy, Sombrero (M 104; NGC 4594), based on XMM-Newton and Chandra observations. A list of 62 XMM-Newton and 175 Chandra discrete X-ray sources is

This presentation focuses on the global hot gas in and around galaxies, especially normal ones like the authors' own, where Chandra observations have led to the first characterization of the spatial, thermal, chemical, and kinetic properties of the gas in their galaxy.

An XMM–Newton observation of the massive edge-on Sb galaxy NGC 2613

We present an XMM-Newton observation of the massive edge-on Sb galaxy NGC 2613. We discover that this galaxy contains a deeply embedded active nucleus with a 0.3-10 keV luminosity of 3.3 x 10 40 erg

X-Raying A2125: A Large-Scale Hierarchical Complex of Galaxies and Hot Gas

We present an 82 ks Chandra ACIS-I observation of a large-scale hierarchical complex, which consists of various clusters/groups of galaxies and low surface brightness X-ray emission at z = 0.247.

Chandra survey of nearby highly inclined disc galaxies – I. X-ray measurements of galactic coronae

We present a systematical analysis of the Chandra observations of 53 nearby highly inclined (i 60 ◦ ) disc galaxies to study the coronae around them. This sample covers a broad range of galaxy

An XMM–Newton and Chandra study of the starburst galaxy IC 10

We present an X-ray study of our nearest starburst galaxy IC 10, based on XMM-Newton and Chandra observations. A list of 73 XMM-Newton and 28 Chandra detections of point-like X-ray sources in the


Models of disk galaxy formation commonly predict the existence of an extended reservoir of accreted hot gas surrounding massive spirals at low redshift. As a test of these models, we use X-ray and Hα

Abstract Galactic X-ray emission is a manifestation of various high-energy phenomena and processes. The brightest X-ray sources are typically accretion-powered objects: active galactic nuclei and


We present Suzaku spectra of X-ray emission in the fields just off the LMC X-3 sight line. O vii, O viii, and Ne ix emission lines are clearly detected, suggesting the presence of an optically thin



Chandra Detection of a Hot Gaseous Corona around the Edge-on Galaxy NGC 4631

We present a Chandra X-ray observation that shows, unambiguously for the first time, the presence of a giant diffuse X-ray-emitting corona around the edge-on disk galaxy NGC 4631. This corona, with a

ROSAT detection of diffuse hot gas in the edge-on galaxy NGC 4631

ROSAT observation is presented of the edge-on spiral galaxy NGC 4631, a nearby Sc/SBd galaxy best known for its extended radio halo. Because of the low foreground Galactic X-ray-absorbing gas column

The Nature of Ultraluminous Compact X-Ray Sources in Nearby Spiral Galaxies

Studies were made of ASCA spectra of seven ultraluminous compact X-ray sources in nearby spiral galaxies: M33 X-8, M81 X-6, IC 342 source 1, Dwingeloo 1 X-1, NGC 1313 source B, and two sources in NGC

Diffuse Ionized Gas in a Sample of Edge-on Galaxies and Comparisons with H I and Radio Continuum Emission

We present Hα images of four edge-on galaxies: NGC 5775, NGC 3044, NGC 4183, and NGC 3556. Our goals are twofold: first, to continue the study of the occurrence and physical properties of extraplanar

High-Resolution Radio Continuum Observations of Edge-on Spiral Galaxies

Radio continuum emission at 20 cm has been observed in a sample of 16 edge-on galaxies, using the VLA in its A configuration. These galaxies were observed recently at lower resolution by Irwin et

Warm ionized gas in the edge-on galaxies NGC 4565 and NGC 4631

We present H-alpha observations of two edge-on galaxies: NGC 4565 and NGC 4631. In contrast to NGC 891, which was studied in a previous paper, neither of these galaxies shows evidence for a smooth,

Radio Emission from an Ultraluminous X-ray Source

Radio emission from an ultraluminous x-ray source in the dwarf irregular galaxy NGC 5408 is discovered, and thex-ray, radio, and optical fluxes as well as the x-rays spectral shape are consistent with beamed relativistic jet emission from a accreting stellar black hole.
