Dark Gaps and Resonances in Barred Galaxies
The Astrophysical JournalDark 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 ...

The Astrophysical Journal, 2023 We analyze TYPHOON long-slit-absorption line spectra of the starburst barred spiral galaxy NGC 1365 obtained with the Progressive Integral Step Method covering an area of 15 kpc ^2 .

Surface photometry of barred spiral galaxies
The Astrophysical Journal, 1990 La photometrie de surface detaillee a ete realisee pour 6 galaxies spirales barrees de premier type en utilisant des plaques photographiques a haute resolution. Les observations et les reductions des donnees sont presentees et les profils azimutaux de la luminosite sont extraits et analyses.

The FEBS Journal, EarlyView.Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.

The Illustris Simulation: Supermassive Black Hole - Galaxy Connection Beyond the Bulge
, 2017 We study the spiral arm morphology of a sample of the local spiral galaxies in the Illustris simulation and explore the supermassive black hole - galaxy connection beyond the bulge (e.g., spiral arm pitch angle, total stellar mass, dark matter mass, and ...

Six New Galactic Orbits of Globular Clusters in a Milky-Way-Like Galaxy [PDF]
, 2007 Absolute proper motions for six new globular clusters have recently been determined. This motivated us to obtain the Galactic orbits of these six clusters both in an axisymmetric Galactic potential and in a barred potential, such as the one of our Galaxy.

Galactic Bars Are Already Mature at Cosmic Noon: Bar Strength and Flatness at z ∼ 1.5
The Astrophysical JournalIn this work, we explore the nature of z > 1 galactic bars. Once thought to be highly transient, our results demonstrate otherwise. Our sample consists of nine massive (>10 ^10.5 M _⊙ ) star-forming barred-spiral galaxies at z _spec ∼ 1.5.

The Astrophysical Journal, 2023 We present a detailed analysis of the structure of the Local Group flocculent spiral galaxy M33, as measured using the Panchromatic Hubble Andromeda Treasury Triangulum Extended Region (PHATTER) survey. Leveraging the multiwavelength coverage of PHATTER,

Starbursts in barred spiral galaxies [PDF]
Astronomy and Astrophysics Supplement Series, 1998 This paper presents optical long-slit spectroscopic observations of 105 barred Markarian IRAS galaxies. These observations are used to determine the spectral type of emission-line regions in the nucleus and along the bar of the galaxies, in order to define a homogeneous sample of Starburst Nucleus Galaxies (SBNGs). Our selection criteria have been very
