Are Disks of Satellites Comprised of Tidal Dwarf Galaxies?

Galaxies, 2021
It was found that satellites of nearby galaxies can form flattened co-rotating structures called disks of satellites or planes of satellites. Their existence is not expected by the current galaxy formation simulations in the standard dark matter-based ...

Modelling ISO Galaxy Counts with Luminosity and Merger Rate Evolution [PDF]

, 1998
We model galaxy evolution in the 6.75 and 15 micron passbands of the ISO satellite, by combining models of galaxy evolution at optical wavelengths (which are consistent with the optical galaxy counts) with observed spectral energy distributions in the ...

Does the fir-radio correlation evolve with redshift in irregular and disk galaxies? [PDF]

Serbian Astronomical Journal, 2021
It was confirmed that there is a strong linear correlation between the thermal far-infrared (FIR) and non-thermal radio emission of the star-forming galaxies.

The Larson-Tinsley Effect in the UV: Interacting vs. `Normal' Spiral Galaxies

, 2010
We compare the UV-optical colors of a well-defined set of optically-selected pre-merger interacting galaxy pairs with those of normal spirals. The shorter wavelength colors show a larger dispersion for the interacting galaxies than for the spirals.

Central star formation and metallicity in CALIFA interacting galaxies

, 2015
We use optical integral-field spectroscopic (IFS) data from 103 nearby galaxies at different stages of the merging event, from close pairs to merger remnants provided by the CALIFA survey, to study the impact of the interaction in the specific star ...

Cores in Dwarf Galaxies from Dark Matter with a Yukawa Potential

, 2010
We show that cold dark matter particles interacting through a Yukawa potential could naturally explain the recently observed cores in dwarf galaxies without affecting the dynamics of objects with a much larger velocity dispersion, such as clusters of ...

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.

Super-star clusters versus OB associations

, 2010
Super Star Clusters (Mecl > 10^5 Msol) are the largest stellar nurseries in our local Universe, containing hundreds of thousands to millions of young stars within a few light years.
