ALMA Weighs Supermassive Black Hole at Center of Distant Spiral Galaxy（图）
ALMA Weighs Supermassive Black Hole Distant Spiral Galaxy
2015/7/13
Supermassive black holes lurk at the center of every large galaxy. These cosmic behemoths can be millions to billions of times more massive than the Sun. Determining just how massive, however, has bee...
CWRU astronomers find new details in first known spiral galaxy
CWRU astronomers first known spiral galaxy
2015/3/4
Case Western Reserve University astronomers peered deep into space to discover new features of a galaxy that’s been sketched and photographed for 170 years.
The researchers were able to see faint plu...
The quantity of dust in a spiral disk can be estimated using the dust's typical emission or the extinction of a known source. In this paper we compare two techniques, one based on emission and one on ...
Pre-peak Ram Pressure Stripping in the Virgo Cluster Spiral Galaxy NGC 4501
NGC 4501 interactions
2014/12/23
VIVA Hi observations of the Virgo spiral galaxy NGC 4501 are presented. The Hi disk is sharply truncated to the southwest, well within the stellar disk. A region of low surface-density gas, which is m...
Hubble Space Telescope Pixel Analysis of the Interacting Face-on Spiral Galaxy NGC 5194 (M51A)
Hubble Space Telescope Pixel Analysis Interacting Face-on Spiral Galaxy NGC 5194 (M51A)
2011/10/19
A pixel analysis is carried out on the interacting face-on spiral galaxy NGC 5194 (M51A), using the HST/ACS images in the F435W, F555W and F814W (BVI) bands. After 4x4 binning of the HST/ACS images to...
HALOGAS: HI Observations and Modeling of the Nearby Edge-on Spiral Galaxy NGC 4244
HALOGAS: HI Observations Modeling Nearby Edge-on Spiral
2011/10/12
We present 21-cm observations and models of the HI kinematics and distribution of NGC 4244, a nearby edge-on Scd galaxy observed as part of the Westerbork Hydrogen Accretion in LOcal GAlaxieS (HALOGAS...
We present results for X-ray point sources in the Sc galaxy NGC 2276, obtained by analyzing Chandra data. The galaxy is known to be very active in many wavelengths, possibly due to gravitational inter...

2010/11/15
We present a wide field survey of satellite galaxies in M106 (NGC 4258)covering a 1.7◦ × 2◦ field around M106 using Canada-France-Hawaii Tele-scope/MegaCam. We find 16 satellite galaxy can...
Importance of far-infrared mapping in a spiral galaxy: AKARI observation of M81
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
The importance of the far-infrared (FIR) mapping is demonstrated for a face-on spiral galaxy, M81, by analyzing its imaging data at 65, 90, and 140 {\mu}m taken by AKARI. Basic products are the dust t...
