IllustrisTNG50 angular momentum maps: tracing the morpho-kinematic evolution of galaxies

Juan Manuel Pacheco-Arias, Benoît Epinat, Philippe Amram +2

Following the first observational study of the two-dimensional spatial distribution of stellar specific angular momentum (sAM) in late-type galaxies, we quantify the morpho-kinemat…

Physical characterization of the local system NGC 1313: A flattening in its chemical abundance by past interactions

Belén Ojeda-Díaz, Sergio Torres-Flores, Daniela E. Olave-Rojas +5

Interacting galaxies provide unique information on morphological transformation, enhanced star formation, and chemical evolution, and thus contribute to understanding the complex e…

New morpho-kinematic classification: The two-dimensional spatial distribution of stellar specific angular momentum in late-type galaxies

Juan Manuel Pacheco-Arias, Philippe Amram, Benoît Epinat +1

The two-dimensional spatial distribution of stellar specific angular momentum (sAM) within galaxies has never been previously analysed. We investigate its morpho-kinematics and its…

WLM: Dynamics of an isolated Dwarf Irregular Galaxy Under Ram Pressure in the Local Group

Neel Kolhe, Francois Hammer, Yanbin Yang +5

WLM is an archetypal dwarf irregular galaxy that has not experienced interactions with major Local Group galaxies within the past 8 Gyr. It has recently been shown that WLM is losi…

Extraplanar emission in isolated edge-on late-type galaxies.II. The H kinematics

Minerva M. Sardaneta, Philippe Amram, Roberto Rampazzo +3

Isolated galaxies are rare yet invaluable for studying secular evolution, as their physical properties can remain largely unaffected by external influences for several billion year…

Investigating the HI distribution and kinematics of ESO444-G084 and [KKS2000]23: New insights from the MHONGOOSE survey

Brenda Namumba, Roger Ianjamasimanana, Bärbel Koribalski +25

We present the HI distribution, kinematics, mass modeling, and disk stability of the dwarf irregular galaxies ESO444-G084 and [KKS2000]23 using high-resolution, high-sensitivity MH…
