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 ...

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.

Zoom-in cosmological hydrodynamical simulation of a star-forming barred, spiral galaxy at redshift z=2 [PDF]
, 2019 Accepted for publication in MNRASWe present gas and stellar kinematics of a high-resolution zoom-in cosmological chemodynamical simulation, which fortuitously captures the formation and evolution of a star-forming barred spiral galaxy, from redshift $z ...

Scalable Automated Detection of Spiral Galaxy Arm Segments
, 2014 Given an approximately centered image of a spiral galaxy, we describe an entirely automated method that finds, centers, and sizes the galaxy and then automatically extracts structural information about the spiral arms. For each arm segment found, we list

ESO 603-G21: A strange polar-ring galaxy [PDF]
, 2001 We present the results of B, V, R surface photometry of ESO603-G21 - a galaxy with a possible polar ring. The morphological and photometric features of this galaxy are discussed.

, 2023 Our vision of galaxies has changed significantly since the era of large galaxy surveys like the Sloan, which gave us extensive statistics with millions of galaxies. The Hubble sequence classification described in Chapter 1 still remains very widely used but has been enriched with broad categories based on color that indicate the recent formation of ...

THE OPACITY OF SPIRAL GALAXY DISKS [PDF]
, 2007 The opacity of foreground spiral disks can be probed from the number of distant galaxies seen through them. To calibrate this number for effects other than the dust extinction, Gonzalez et al. (1998) developed the "Synthetic Field Method". A synthetic field is an extincted Hubble Deep Field added to the science field.

The first detection of Far-Infrared emission associated with an extended HI disk. The case of NGC 891 [PDF]
, 2003 Spiral galaxies in the Local Universe are commonly observed to be embedded in extended disks of neutral hydrogen - the so called ``extended HI disks''.
