The connection between surface brightness and satellite systems for central galaxies through IllustrisTNG

open access: yesAstronomy & Astrophysics
We analysed different properties of central low-surface-brightness galaxies (LSBGs) and their satellite systems using the simulation TNG100 in order to deepen our understanding of the formation mechanism of LSBGs in a Λ cold dark matter cosmology.

The Dominance of Metal-Rich Streams in Stellar Halos: A Comparison Between Substructure in M31 and Lambda-CDM Models [PDF]

open access: yes, 2009
Extensive photometric and spectroscopic surveys of the Andromeda galaxy (M31) have discovered tidal debris features throughout M31's stellar halo. We present stellar kinematics and metallicities in fields with identified substructure from our on-going ...

The stellar populations of low surface brightness galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1999
Near-infrared (NIR) K' images of a sample of five low surface brightness disc galaxies (LSBGs) were combined with optical data, with the aim of constraining their star formation histories. Both red and blue LSBGs were imaged to enable comparison of their stellar populations.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

The Effects of Starburst Activity on Low Surface Brightness Disk Galaxies

open access: yes, 1998
Although numerous simulations have been done to understand the effects of intense bursts of star formation on high surface brightness galaxies, few attempts have been made to understand how localized starbursts would affect both the color and surface ...

The dependence of HII region properties on global and local surface brightness within galaxy discs [PDF]

open access: yes, 2008
Using B, R, and H-alpha images of roughly equal-sized samples of low surface brightness (LSB) and high surface brightness (HSB) galaxies (~40 galaxies apiece), we have explored the dependence of HII region properties on local and global disc surface ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Distances to the Origem and the Monoceros loops [PDF]

open access: yesSerbian Astronomical Journal, 1998
Using the Supernova Remnants (SNR) hypothesis for the radio loops, distances of the Origem and the Monoceros loops were calculated from the surface brightness and the angular diameters at 1420 MHz.
