Spiral galaxies in the SAURON survey [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe discuss some recent integral field spectroscopy using the SAURON instrument of a sample consisting of 24 early-type spirals, part of the SAURON Survey, and 18 late-type spirals. Using 2-dimensional maps of their stellar radial velocity, velocity dispersion, and absorption line strength, it is now much easier to understand the nature of ...

DETECTION OF A LUMINOUS HOT X-RAY CORONA AROUND THE MASSIVE SPIRAL GALAXY NGC 266 [PDF]
, 2013 The presence of luminous hot X-ray coronae in the dark matter halos of massive spiral galaxies is a basic prediction of galaxy formation models. However, observational evidence for such coronae is very scarce, with the first few examples having only been

Isolated Galaxies versus Interacting Pairs with MaNGA
Galaxies, 2015 We present preliminary results of the spectral analysis on the radial distributions of the star formation history in both a galaxy merger and a spiral isolated galaxy observed with MaNGA.

Are Passive Spiral Galaxies Truly "Passive" and "Spiral"? : Near-Infrared Perspective [PDF]
Mon.Not.Roy.Astron.Soc. 352 (2004) 815, 2004 Passive spiral galaxies -- unusual galaxies with spiral morphology without any sign of on-going star formation -- have recently been discovered to exist preferentially in cluster infalling regions (at about the virial radius, or at a local galaxy density of $\sim 1$ Mpc$^{-2}$). The discovery directly connects the passive spiral galaxies to the cluster

The Galaxy in Context: Structural, Kinematic, and Integrated Properties [PDF]
, 2016 Our Galaxy, the Milky Way, is a benchmark for understanding disk galaxies. It is the only galaxy whose formation history can be studied using the full distribution of stars from faint dwarfs to supergiants.

The dust energy balance in the edge-on spiral galaxy NGC 4565 [PDF]
, 2012 We combine new dust continuum observations of the edge-on spiral galaxy NGC 4565 in all Herschel/Spectral and Photometric Imaging Receiver (250, 350 and 500 mu m) wavebands, obtained as part of the Herschel Reference Survey, and a large set of ancillary ...

Radio AGN in spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Radio AGN in the nearby Universe are more likely to be found in galaxies with early-type morphology, the detection rate in spiral or late-type galaxies (LTGs) being around an order of magnitude lower. We combine the mJy Imaging VLBA Exploration at 20 cm (mJIVE-20) survey with the Sloan Digital Sky Survey, to study the relatively rare population of AGN ...

The profiles of bars in spiral galaxies
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT We present an analysis of major-axis surface-brightness profiles of bars in a volume-limited sample of 182 barred spiral galaxies, using Spitzer 3.6 $\mu$m images. Unlike most previous studies, we use the entire bar profile, and we classify profiles into four categories.

METALLICITY GRADIENT OF A LENSED FACE-ON SPIRAL GALAXY AT REDSHIFT 1.49 [PDF]
, 2011 We present the first metallicity gradient measurement for a grand-design face-on spiral galaxy at z ∼ 1.5. This galaxy has been magnified by a factor of 22× by a massive, X-ray luminous galaxy cluster MACS J1149.5+2223 at z = 0.544. Using the Laser Guide
