HOT GASEOUS CORONAE AROUND SPIRAL GALAXIES: PROBING THE ILLUSTRIS SIMULATION [PDF]
, 2015 The presence of hot gaseous coronae around present-day massive spiral galaxies is a fundamental prediction of galaxy formation models. However, our observational knowledge remains scarce, since to date only four gaseous coronae have been detected around ...

ULTRALIGHT SCALARS AND SPIRAL GALAXIES [PDF]
Modern Physics Letters A, 2001 We study some possible astrophysical implications of a very weakly coupled ultralight dilaton-type scalar field. Such a field may develop an (approximately stable) network of domain walls. The domain wall thickness is assumed to be comparable with the thickness of the luminous part of the spiral galaxies. The walls provide trapping for galactic matter.

Discovery of rare double-lobe radio galaxies hosted in spiral galaxies [PDF]
, 2015 Double-lobe radio galaxies in the local Universe have traditionally been found to be hosted in elliptical or lenticular galaxies. We report the discovery of four spiral-host double-lobe radio galaxies (J0836+0532, J1159+5820, J1352+3126 and J1649+2635 ...

Spiral Galaxies as Chiral Objects? [PDF]
Astrophysics and Space Science, 2006 Spiral galaxies show axial symmetry and an intrinsic 2D-chirality. Environmental effects can influence the chirality of originally isolated stellar systems and a progressive loss of chirality can be recognised in the Hubble sequence. We point out a preferential modality for genetic galaxies as in microscopic systems like aminoacids, sugars or neutrinos.

Near-Infrared Surface Photometry of Bulges and Disks of Spiral Galaxies : The Data [PDF]
, 1997 : We present optical and near-infrared (NIR) surface brightness and colour profiles,in bands ranging from U to K, for the disk and bulge components of a complete sample of 30 nearby S0 to Sbc galaxies with inclinations larger than 50 degrees. We describe

SUPERLUMINOUS SPIRAL GALAXIES [PDF]
, 2015 We report the discovery of spiral galaxies that are as optically luminous as elliptical brightest cluster galaxies, with r-band monochromatic luminosity Lr = 8–14L* (4.3–7.5 × 1044 erg s−1).

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.

Probing the Low-Mass End of the Black Hole Mass Function via a Study of Faint Local Spiral Galaxies
, 2022 We present an analysis of the pitch angle distribution function (PADF) for nearby galaxies and its resulting black hole mass function (BHMF) via the well-known relationship between pitch angle and black hole mass.
