Radio structures in QSO-galaxy pairs [PDF]

open access: yes, 1990
It is now generally agreed that if quasars and nearby low redshift galaxies are associated, then there should be luminous connections between them.

CFHTLenS: Higher-order galaxy-mass correlations probed by galaxy-galaxy-galaxy lensing

open access: yes, 2013
We present the first direct measurement of the galaxy-matter bispectrum as a function of galaxy luminosity, stellar mass, and SED type. Our analysis uses a galaxy-galaxy-galaxy lensing technique (G3L), on angular scales between 9 arcsec to 50 arcmin, to ...

Disney's Auteur Problem: Framing Corporate Creativity in a Galaxy Far, Far Away

open access: yesThe Journal of Popular Culture, EarlyView.
ABSTRACT At its core, Star Wars is a franchise George Lucas has led via his auteur vision. Since Lucas handed over the franchise reins to Disney, the company has courted several other auteurs to direct new entries in the series—each of those endeavors ended problematically.

A new algorithm for the detection of intercluster galaxy filaments using galaxy orientation alignments

open access: yes, 2005
We present a new algorithm for detecting intercluster galaxy filaments based upon the assumption that the orientations of constituent galaxies along such filaments are non-isotropic.

Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Radio line and continuum observations of quasar-galaxy pairs and the origin of low reshift quasar absorption line systems [PDF]

open access: yes, 1990
There are a number of known quasars for which our line of sight to the high redshift quasar passes within a few Holmberg radii of a low redshift galaxy.

Reduction of the Bar Fraction in Paired Galaxies in the SDSS

open access: yesThe Astrophysical Journal
We investigate the bar fraction in galaxy pairs from the Sloan Digital Sky Survey to assess how galaxy interactions affect bar structures. Compared to isolated galaxies, close pairs exhibit a significantly reduced bar fraction at projected separations ...

Regulation by the Transcriptional Regulator YdcI in E. coli and (p)ppGpp‐Dependent Activation of ydcI Expression

open access: yesMolecular Microbiology, EarlyView.
YdcI, a LysR‐type transcription regulator in Escherichia coli, regulates loci like iraP and mqo. Its expression is induced by (p)ppGpp under stress conditions, and protein levels rise during mid‐exponential growth, connecting its role to stress response and metabolism control. ABSTRACT YdcI, a LysR‐type transcription regulator, has been associated with

A SURVEY OF FAINT GALAXY PAIRS

open access: yes, 1994
A sample of faint, V-magnitude selected, galaxy pairs, having physical separations less than similar to 20 h(-1) kpc, is used to examine the rise in the merger rate with redshift and the statistical relations between close pairs and the field galaxy ...

VODKA-JWST: Synchronized Growth of Two Supermassive Black Holes in a Massive Gas Disk? A 3.8 kpc Separation Dual Quasar at Cosmic Noon with the NIRSpec Integral Field Unit

open access: yesThe Astrophysical Journal
The search for dual supermassive black holes (SMBHs) is of immense interest in modern astrophysics. Galaxy mergers may fuel and produce SMBH pairs. Actively accreting SMBH pairs are observed as dual quasars, which are vital probes of SMBH growth.
