The edge of the Galaxy [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We use cosmological simulations of isolated Milky Way (MW)-mass galaxies, as well as Local Group (LG) analogues, to define the ‘edge’ – a caustic manifested in a drop in density or radial velocity – of Galactic-sized haloes, both in dark matter and in stars.

The Origin of the Mass-Metallicity Relation: Insights from 53,000 Star-forming Galaxies in the Sloan Digital Sky Survey [PDF]

open access: yes, 2004
We utilize Sloan Digital Sky Survey imaging and spectroscopy of ~53,000 star-forming galaxies at z ~ 0.1 to study the relation between stellar mass and gas-phase metallicity.

Equipartition Jet Model for the Seyfert 1 Galaxy 3C120 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2003
The motion of 3C120 Jet relative to the core is reasonably uniform and the VLBI scale jet connects outwards to a VLA ˜ 100 kpc scale. We measured the jet width variation from the center and found some indication of a power law which indicates the jet ...

Surface Density of Disk Galaxies in MOND

open access: yesUniverse, 2023
In this paper, we extend a paper by Milgrom (2009, MNRAS 398, 1023) dealing with the existence of a quasi-universal surface density for object of all mass and structure, if they are in the Newtonian regime, i.e., that their mean acceleration is larger ...

The physical properties of star-forming galaxies in the low-redshift universe [PDF]

open access: yes, 2003
We present a comprehensive study of the physical properties of ∼ 10 5 galaxies with measurable star formation in the Sloan Digital Sky Survey (SDSS). By comparing physical information extracted from the emission lines with continuum properties, we build ...

Spirality: A Novel Way to Measure Spiral Arm Pitch Angle

open access: yesGalaxies, 2022
We present the MATLAB code Spirality, a novel method for measuring spiral arm pitch angles by fitting galaxy images to spiral templates of known pitch. Computation time is typically on the order of 2 min per galaxy, assuming 8 GB of working memory.

The AMIGA sample of isolated galaxies. V. Quantification of the isolation [PDF]

open access: yes, 2007
The AMIGA project aims to build a well defined and statistically significant reference sample of isolated galaxies in order to estimate the environmental effects on the formation and evolution of galaxies.
