Interpreting Debris from Satellite Disruption in External Galaxies [PDF]
The Astrophysical Journal, 2001 We examine the detectability and interpretation of debris trails caused by satellite disruption in external galaxies using semi-analytic approximations for the dependence of streamer length, width and surface brightness on satellite and primary galaxy characteristics.

Potential impact of the Sagittarius dwarf galaxy on the formation of young O-rich stars [PDF]
Nature CommunicationsThe Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notable star formation events over the past 4 Gyr, likely triggered by ...

Formation of Transitional cE/UCD Galaxies through Massive/Dwarf Disc Galaxy Mergers
Galaxies, 2023 The dynamics of the merger of a dwarf disc galaxy with a massive spiral galaxy of the Milky Way type were studied in detail. The remnant of such interaction after numerous crossings of the satellite through the disc of the main galaxy was a compact ...

A Census of Dwarf Galaxy Satellites around LMC-mass Galaxy NGC 2403
The Astrophysical JournalWe present the first comprehensive census of the satellite population around a Large Magellanic Cloud stellar-mass galaxy, as part of the Magellanic Analog Dwarf Companions and Stellar Halos (MADCASH) survey. We have surveyed NGC 2403 ( D = 3.0 Mpc) with

The Astrophysical Journal Letters, 2023 The quenched fraction of satellite galaxies is aligned with the orientation of the halo’s central galaxy, such that on average, satellites form stars at a lower rate along the major axis of the central.

Dynamical Friction on Satellite Galaxies [PDF]
Publications of the Astronomical Society of Japan, 2006 Abstract For a rigid model satellite, Chandrasekhar’s dynamical friction formula describes the orbital evolution quite accurately, when the Coulomb logarithm is chosen appropriately. However, it is not known if the orbital evolution of a real satellite with the internal degree of freedom can be described by the dynamical friction formula.

Satellites and haloes of dwarf galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 We study the abundance of satellite galaxies as a function of primary stellar mass using the SDSS/DR7 spectroscopic catalogue. In contrast with previous studies, which focussed mainly on bright primaries, our central galaxies span a wide range of stellar mass, 10^7.5 < M_*^pri/M_sun < 10^11, from dwarfs to central cluster galaxies.

THE LOPSIDED DISTRIBUTION OF SATELLITE GALAXIES [PDF]
The Astrophysical Journal, 2016 ABSTRACT The distribution of smaller satellite galaxies around large central galaxies has attracted attention because peculiar spatial and kinematic configurations have been detected in some systems. A particularly striking example of such behavior is seen in the satellite system of the Andromeda galaxy, where around 80% are on the near ...
