Identification and Analysis of Galactic Bars in DESI Legacy Imaging Surveys

The Astrophysical Journal
We present a comprehensive study of bar structures in the local universe using data from the DESI Legacy Imaging Surveys. Through isophotal analysis of 232,142 galaxies, we identify bars and classify them into strong and weak categories based on ...

Bars do drive spiral density waves

, 2010
Recently, Buta etal. (2009) examined the question "Do Bars Drive Spiral Density Waves?", an idea supported by theoretical studies and also from a preliminary observational analysis Block etal (2004).

Simultaneous inhibition of TRIM24 and TRIM28 sensitises prostate cancer cells to antiandrogen therapy, decreasing VEGF signalling and angiogenesis

Molecular Oncology, Volume 19, Issue 10, Page 2797-2821, October 2025.
TRIM24 and TRIM28 are androgen receptor (AR) coregulators which exhibit increased expression with cancer progression. Both TRIM24 and TRIM28 combine to influence the response of castrate‐resistant prostate cancer (CRPC) cells to AR inhibitors by mediating AR signalling, regulation of MYC and upregulating VEGF to promote angiogenesis. Castrate‐resistant

Luminosities of Barred and Unbarred S0 Galaxies

, 2012
Lenticular galaxies with M_B < -21.5 are almost exclusively unbarred, whereas both barred and unbarred objects occur at fainter luminosity levels. This effect is observed both for objects classified in blue light, and for those that were classified in ...

α‐Helix‐Driven Regulation of Aqueous Circularly Polarized Luminescence in Homopolypeptide Self‐Assembly

Aggregate, Volume 6, Issue 10, October 2025.
We explore the hierarchical chirality transfer in self‐assembled fluorescent homopolypeptide systems for achieving aqueous circularly polarized luminescence (CPL), and reveal the α‐helix‐dominated CPL regulation mechanism during the self‐assembly process .

Impacts of Bar-driven Shear and Shocks on Star Formation

The Astrophysical Journal
Bars drive gas inflow. As the gas flows inward, shocks and shear occur along the bar dust lanes. Such shocks and shear can affect the star formation (SF) and change the gas properties.

Do Strong Bars Exhibit Strong Noncircular Motions?

The Astrophysical Journal
Galactic bars induce characteristic motions deviating from pure circular rotation, known as noncircular motions. As bars are nonaxisymmetric structures, stronger bars are expected to show stronger noncircular motions.
