A search for the most massive galaxies: double trouble? [PDF]

, 2005
We describe the results of a search for galaxies with large ({approx}> 350 kms{sup -1}) velocity dispersions. The largest systems we have found appear to be the extremes of the early-type galaxy population: compared to other galaxies with similar ...

Do minor interactions trigger star formation in galaxy pairs? [PDF]

, 2023
We analyze the galaxy pairs in a set of volume limited samples from the SDSS to study the effects of minor interactions on the star formation rate (SFR) and colour of galaxies.

A new sample of bright galaxy pairs in UZC

, 2006
We present a new sample of bright galaxy pairs extracted applying an objective selection code to the UZC catalog. The sample is volume-limited to Mzw = -18.9 +5 log {h} and contains 89 galaxy pairs.

Close galaxy pairs with accurate photometric redshifts [PDF]

, 2020
Context. Studies of galaxy pairs can provide valuable information to jointly understand the formation and evolution of galaxies and galaxy groups. Consequently, taking the new high-precision photo-z surveys into account, it is important to have reliable ...

Fine-grained Morphological Study of Galaxy Pairs: A Human-in-the-loop Self-supervised Classification Framework

The Astronomical Journal
Galaxy pairs, as key probes for studying galaxy formation and evolution, provide a unique window for observing galaxy interactions, including the associated exchange of material and related galaxy formation activities.

Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions

Advanced Materials, EarlyView.
This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

Intervelocity of galaxy pairs in ΛCDM

, 2022
Context. Observational studies of pairs of galaxies have uncovered that their differential line-of-sight velocities indicate the presence of a peak in their three-dimensional (3D) intervelocity distribution at 130−150 km s−1.
