THE CENTRAL REGION OF THE BARRED SPIRAL GALAXY NGC 1097 PROBED BY AKARI NEAR-INFRARED SPECTROSCOPY [PDF]
, 2012 With the Infrared Camera on board AKARI, we carried out near-infrared (2.5–5.0 μm) spectroscopy of the central kiloparsec region of the barred spiral galaxy, NGC 1097, categorized as Seyfert 1 with a circumnuclear starburst ring.

ADF22-WEB: A giant barred spiral starburst galaxy in the z = 3.1 SSA22 protocluster core [PDF]
Nippon Tenmon Gakkai obun kenkyu hokokuIn the present-day universe, the most massive galaxies are ellipticals located in the cores of galaxy clusters, harboring the heaviest super-massive black holes (SMBHs).

Zoom-in cosmological hydrodynamical simulation of a star-forming barred, spiral galaxy at redshift z=2 [PDF]
Monthly notices of the Royal Astronomical Society, 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 ...

A New Statistical Analysis of the Morphology of Spiral Galaxies [PDF]
The Astronomical JournalMorphology is the starting point for understanding galaxies. Elmegreen et al. classified spiral galaxies into flocculent, multiple-arm, and grand-design galaxies based on the regularity of their spiral arm structure.

Star formation efficiency in the Barred Spiral Galaxy NGC 4303 [PDF]
, 2010 We present new $^{12}$CO(J=1-0) observations of the barred galaxy NGC 4303 using the Nobeyama 45m telescope (NRO45) and the Combined Array for Research in Millimeter-wave Astronomy (CARMA). The H$\alpha$ images of barred spiral galaxies often show active

Pattern speeds in barred spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1988 Des simulations a N corps montrent comment la barre des galaxies SB tourne, se separe de la structure spirale, la rattrappe et se connecte de nouveau au bras spiraux. Cela provient de vitesses de rotation differentes pour la barre et les bras spiraux.

Formation of the spiral structure in SB galaxies [PDF]
Astronomy Letters, 2001 We consider a scenario of formation of the spiral structure in barred galaxies. This scenario includes the new non-resonant mechanism of elongation of spirals, due to the characteristic behaviour of the gravitational potential beyond the principal spiral arms.

Stellar populations in the center of barred spiral galaxies [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe show observations obtained with the integral field spectrometer OASIS for the centers of a sample of barred galaxies. The high spatial resolution of the instrument allows to distinguish spatially some structures within these regions as defined by stellar populations of different ages and metallicities.
