Dark Gaps and Resonances in Barred Galaxies

open access: yesThe Astrophysical Journal
Dark gaps, low surface brightness regions along the bar minor axis, are expected to form as a consequence of secular evolution in barred galaxies. Although several studies have proposed links between dark gap locations and dynamical resonances, the ...

Radio Jet Feedback on the Inner Disk of Virgo Spiral Galaxy Messier 58

open access: yesThe Astrophysical Journal
Spitzer spectral maps reveal a disk of highly luminous, warm (>150 K) H _2 in the center of the massive spiral galaxy Messier 58, which hosts a radio-loud active galactic nucleus (AGN). The inner 2.6 kpc of the galaxy appears to be overrun by shocks from

Modeling the Radial Color Profile of M31

open access: yesOpen Astronomy, 2003
We present a preliminary study of a fragment of the radial color profile of the spiral galaxy M 31 in terms of 2-D model accounting for internal extinction in the disk. The two stellar population disk model was assumed.

The Redshift of GRB 190829A/SN 2019oyw: A Case Study of GRB-SN Evolution

open access: yesThe Astrophysical Journal
The nearby long gamma-ray burst (GRB) 190829A was observed using the Hubble Space Telescope/Wide Field Camera 3/infrared grisms about four weeks to 500 days after the burst.

Can the Dynamo of Spiral-arm Galaxies Be Explained by Anisotropic Conductivity?

open access: yesThe Astrophysical Journal
The possibility of generating a magnetic field by a dynamo effect with anisotropic electrical conductivity rather than turbulent flow has been demonstrated theoretically and experimentally.
