COSMOS-Web: The Role of Galaxy Interactions and Disk Instabilities in Producing Starbursts at z < 4
The Astrophysical JournalWe study of the role of galaxy–galaxy interactions and disk instabilities in producing starburst activity in galaxies out to z = 4. For this, we use a sample of 387 galaxies with robust total star formation rate measurements from Herschel, gas masses ...

The Astrophysical Journal, 2023 Dwarf galaxies located in extremely underdense cosmic voids are excellent test beds for disentangling the effects of large-scale environments on galaxy formation and evolution. We present the first results of the Dwarfs in Void Environments Survey, which

A study of galaxy interactions
, 2014 This work describes the in-depth study of two systems of interacting galaxies, namely Arp 10 and VII Zw466. Both systems belong to a special group of interacting galaxies known as collisional ring and ring-like galaxies. A typical ring galaxy emerges when a companion galaxy passes through or near the center of a larger rotating disk galaxy driving ring-

Galaxy Harassment—Interactions for the 90s [PDF]
Symposium - International Astronomical Union, 1999 The origin of the Hubble sequence remains a long-standing puzzle in astronomy. Giant galaxies range from slowly-rotating dense ellipticals to thin late-type spiral disks. At the faint end, there are two distinct classes of “ellipticals/spheroids” that are easily separated in plots of nearly any two of their properties, such as central surface ...

Aggregate, EarlyView.By employing new protein‐templated AIEgen Ir@BSA as the phosphorescence signal indicator and papain as the biomolecular recognition element, a straightforward protocol for Cys C quantitation has been developed. On‐site quantitation of Cys C in clinical serum samples has been successfully demonstrated using a smartphone‐based portable phosphorescence ...

Self-rotation of emitting galaxies without dark matter
European Physical Journal C: Particles and Fields, 2021 Temporal derivatives of the attracting mass in Newton’s law of distant interactions can balance the centripetal and centrifugal accelerations for the rotating periphery of a spiral galaxy.

The nature of obscuration in AGN: II. insights from clustering properties
, 2014 Based on large optical and mid-infrared (IR) surveys, we investigate the relation between nuclear activity in local Seyfert 2 galaxies and galaxy interactions using a statistical neighbour counting technique.

Aggregate, EarlyView.Tau amyloid corona‐shelled nanoparticles (TACONs) were synthesized by incubating gold nanoparticles (AuNPs) with tau monomers that had been pre‐reacted with heparin. These TACONs represent a promising high‐throughput screening platform for identifying tau oligomer degraders as potential therapeutic agents for Alzheimer's disease.

Anatomy of the Star Formation in a Tidally Disturbed Disk Galaxy: NGC 3718
The Astrophysical JournalWe present a UV, optical, and near-IR study of the star-forming complexes in the nearby peculiar galaxy NGC 3718, using Ultraviolet Imaging telescope, Galaxy Evolution Explorer, Spitzer, and DECam Legacy Survey imaging data.
