The Astrophysical Journal Letters, 2023 Extreme emission line galaxies (EELGs), where nebular emissions contribute 30%–40% of the flux in certain photometric bands, are ubiquitous in the early Universe ( z > 6).

TeV Diffuse Emission From the Inner Galaxy
Frontiers in Astronomy and Space Sciences, 2018 The TeV diffuse emission from the Galactic plane is produced by multi TeV electrons and nuclei interacting with radiation fields and ambient gas, respectively. Measurements of the TeV diffuse emission help constrain CR origin and transport properties. We

Scale Interactions and Galaxy Evolution [PDF]
Astrophysics and Space Science, 2003 To understand galaxies and their evolution, it is necessary to describe how the different scales interact: how the microscopic physics, such as star formation, or the large scale physics, such as galaxy interactions may modify the galaxy global shapes.

S8 Tension in the Context of Dark Matter–Baryon Scattering
The Astrophysical Journal Letters, 2023 We explore an interacting dark matter (IDM) model that allows for a fraction of dark matter (DM) to undergo velocity-independent scattering with baryons. In this scenario, structure on small scales is suppressed relative to the cold DM scenario.

Probing the Physics of Interacting Galaxies
Astrophysics and Space Science, 2003 Both Arp 140 and Arp 104 reveal extended tidal tails in the HI. The Halpha and FIR fluxes of Arp 140 yield similar SFR of ~0.8 solar masses per year. In contrast the Halpha flux of Arp 104 yields a SFR of ~0.05 solar masses per year, ~ 20 times smaller than that obtained from the FIR flux.

The Radio Emission of Interacting Galaxies [PDF]
Symposium - International Astronomical Union, 1982 Gravitational interaction is a straightforward interpretation of some of the peculiar optical morphologies shown by galaxies. There have also been attempts to study the effects of a gravitational interaction on the radio continuum emission. Statistically, the central radio sources (inner 1 kpc) in interacting spiral galaxies are about three times ...

Hidden Interaction in SBO galaxies [PDF]
International Astronomical Union Colloquium, 1990 Galaxies, like plants, show a large variety of grafts: an individual of some type connects physically with a neighborhood of same or different type. The effects of these interactions between galaxies have a broad range of morphologies depending, among other quantities, on the distance of the closest approach between systems and the relative size of the

Gasdynamics and Starbursts in Interacting Galaxies [PDF]
Symposium - International Astronomical Union, 1999 The onset of gaseous inflows and central activity in interacting galaxies is driven largely by induced bars in the host galaxies. The stability of galaxies against growing bar modes is a direct function of their structural properties — galaxies with central bulges or low disk surface densities are more stable against central starbursts than are ...
