Red Fraction Among Satellite Galaxies with Disk-like Light Profiles: Evidence for Inflow in the H I Disk [PDF]

, 2010
The relationships between color, characterized with respect to the g – r red sequence; stellar structure, as determined using the i-band Sérsic index; and group membership are explored using the Sloan Digital Sky Survey (SDSS).

Preserving evidence integrity in full file system extractions: Assessing hash inconsistencies and potential solutions

Journal of Forensic Sciences, EarlyView.
Abstract Smartphone manufacturers' enhanced privacy and security measures, such as File‐Based Encryption (FBE), have disrupted traditional data extraction techniques, necessitating the adoption of Full File System Extraction (FFS). FFS requires booting a smartphone, decrypting its UserData partition, and accessing files individually, a process that ...

An Optimal Strategy for Accurate Bulge-to-disk Decomposition of Disk Galaxies

, 2017
The development of two-dimensional (2D) bulge-to-disk decomposition techniques has shown their advantages over traditional one-dimensional (1D) techniques, especially for galaxies with non-axisymmetric features.

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

Computer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

Structural Parameters of Thin and Thick Disks in Edge-On Disk Galaxies

, 2005
We analyze the global structure of 34 late-type, edge-on, undisturbed, disk galaxies spanning a wide range of mass. We measure structural parameters for the galaxies using two-dimensional least-squares fitting to our $R$-band photometry. The fits require

Properties of simulated Milky Way-mass galaxies in loose group and field environments [PDF]

, 2012
We test the validity of comparing simulated field disk galaxies with the empirical properties of systems situated within environments more comparable to loose groups, including the Milky Way's Local Group.

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Disk Galaxies at High Redshift? [PDF]

Proceedings of the International Astronomical Union, 2007
AbstractThe successful implementation of integral field near-infrared spectrographs fed by adaptive optics is providing unprecedented views of gas motions within galaxies at redshifts z = 2 − 3, when the universe was forming stars at its peak rate. A complex picture of galaxy kinematics is emerging, with inflows, rotation within sometimes extended and ...

Enhanced dust heating in the bulges of early-type spiral galaxies [PDF]

, 2010
Stellar density and bar strength should affect the temperatures of the cool (T ~ 20–30 K) dust component in the inner regions of galaxies, which implies that the ratio of temperatures in the circumnuclear regions to the disk should depend on Hubble type.

Compact Quiescent Galaxies at Intermediate Redshifts

, 2014
From several searches of the area common to the Sloan Digital Sky Survey and the United Kingdom Infrared Telescope Infrared Deep Sky Survey, we have selected 22 luminous galaxies between $z \sim$ 0.4 and $z \sim$ 0.9 that have colors and sizes similar to
