CO Multi-line Imaging of Nearby Galaxies (COMING). III. Dynamical effect on molecular gas density and star formation in the barred spiral galaxy NGC 4303 [PDF]
Nippon Tenmon Gakkai obun kenkyu hokoku, 2019 We present the results of $^{12}\textrm{C}$$\textrm{O}$(J = 1–0) and $^{13}\textrm{C}$$\textrm{O}$(J = 1–0) simultaneous mappings toward the nearby barred spiral galaxy NGC 4303 as part of the CO Multi-line Imaging of Nearby Galaxies (COMING) project ...

AGN spiral galaxies in groups: effects of bars [PDF]
, 2014 We explore properties of barred active spiral galaxies in groups selected from the SDSS-DR7, with the aim of assessing the effects of bars on AGN and the role of the high density environment.

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.

The Mass Dependence of Star Formation Histories in Barred Spiral Galaxies [PDF]
, 2016 We performed a series of 29 gasdynamical simulations of disc galaxies, barred and unbarred, with various stellar masses, to study the impact of the bar on star formation history.

Herschel and Odin observations of H2O, CO, CH, CH+, and [N II] in the barred spiral galaxy NGC 1365 [PDF]
Astronomy & Astrophysics, 2021 Context. The Odin satellite is now into its twentieth year of operation, much surpassing its design life of two years. One of its major astronomical pursuits was the search for and study of water vapor in diverse regions of the Solar System and the Milky

Spiral structure in barred galaxies. Observational constraints to spiral arm formation mechanisms [PDF]
Monthly notices of the Royal Astronomical Society, 2018 A method, which we have developed for determining corotation radii, has allowed us to map in detail the radial resonant structures of barred spiral galaxies.

EFFECTS OF SPIRAL ARMS ON STAR FORMATION IN NUCLEAR RINGS OF BARRED-SPIRAL GALAXIES [PDF]
, 2014 We use hydrodynamic simulations to study the effect of spiral arms on the star formation rate (SFR) in nuclear rings of barred-spiral galaxies. We find that spiral arms can be an efficient means of gas transport from the outskirts to the central parts ...

The Astrophysical Journal Letters, 2023 JWST/Mid-Infrared Instrument imaging of the nearby galaxies IC 5332, NGC 628, NGC 1365, and NGC 7496 from PHANGS reveals a richness of gas structures that in each case form a quasi-regular network of interconnected filaments, shells, and voids.

Formation of Major Types of Galaxies Based on the Energy Circulation Theory
Reports in Advances of Physical Sciences, 2022 The standard cosmology can answer almost nothing about how the structure of a galaxy is formed. It expects a supermassive black hole at the center and dark matter in the halo to explain the circulation of stars and its velocity.

INVESTIGATING THE NUCLEAR ACTIVITY OF BARRED SPIRAL GALAXIES: THE CASE OF NGC 1672 [PDF]
, 2011 We have performed an X-ray study of the nearby barred spiral galaxy NGC 1672, primarily to ascertain the effect of the bar on its nuclear activity.
