. As a result of our statistical study of 540 edgeon galaxies, we present here the images and preliminary statistical analysis of a sub-sample of 60 galaxies, that were selected to be S-type warped spirals.

Anaerobic digester metagenomes revealed diverse resistance‐associated annotations and antibiotic target loci, highlighting their potential role in environmental AMR surveillance. The findings emphasise the need for cautious interpretation of resistome profiles and further host‐resolved analyses to determine the mobility and clinical relevance of ...

Spiral structure in external galaxies [PDF]
The need for observing at least four different categories of optical objects for a satisfactory definition of optical spiral structure is emphasized. A sequence of optical form-types for the description of spiral structure is outlined. A pronounced difference in the nature of the spiral structure of the outer and inner parts of Messier 33 is ...

DESI EDR: Calibrating the Tully–Fisher Relationship with the DESI Peculiar Velocity Survey
We calibrate the Tully–Fisher relation (TFR) with data from the DESI Peculiar Velocity (PV) Survey taken during the Survey Validation (SV) period of the DESI galaxy redshift survey.

Genomic Signatures of Endemic Pathogen Exposure in a Declining Amphibian
ABSTRACT Endemic wildlife diseases can impose strong selection on threatened populations, yet whether persistence is associated with adaptive genomic responses remains poorly understood. We tested whether long‐term exposure to Batrachochytrium dendrobatidis (Bd) following population declines has left detectable selection signatures in the genome of the

Magnetic fields in spiral galaxies [PDF]
Radio synchrotron emission is a powerful tool to study the strength and structure of magnetic fields in galaxies. Unpolarized synchrotron emission traces isotropic turbulent fields which are strongest in spiral arms and bars (20-30 μG) and in central starburst regions (50-100 μG).

Some statistical properties of spiral galaxies
This paper presents some statistical correlations of 72 northern spiral galaxies. The results show that early-type spirals that are brighter, and thicker, and the axis ratios (H-z/H-r) of the disk tend to be smaller along the Hubble sequence.

Simulating molecular cloud regulated star formation in Galaxies [PDF]
This thesis is primarily concerned with understanding the process of galaxy formation via the simulation of the interstellar medium, star formation and supernova feedback.
