COSMOS-Web: The Role of Galaxy Interactions and Disk Instabilities in Producing Starbursts at z < 4

open access: yesThe Astrophysical Journal
We 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 ...

PES‐trotter: A Cross‐Platform Open‐Source Application for the Analysis of Molecular Processes on 3D Potential‐Energy Landscapes

open access: yesJournal of Computational Chemistry, Volume 47, Issue 14, 30 May 2026.
PES‐trotter is a cross‐platform open‐source application for the exploration and analysis of 3D potential‐energy landscapes associated to molecular systems. Along with video‐game‐like exploration, it allows plotting energy profiles from custom paths, computing critical points and minimum‐energy paths, and playing back dynamical trajectories. PES‐trotter

Secondary evolution of galaxies investigated by N-body simulations

open access: yes, 2008
In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

The SAMI Galaxy Survey: revisiting galaxy classification through high-order stellar kinematics [PDF]

open access: yes, 2017
Recent cosmological hydrodynamical simulations suggest that integral field spectroscopy can connect the high-order stellar kinematic moments h3 (~skewness) and h4 (~kurtosis) in galaxies to their cosmological assembly history.

Kinematics of edge-on galaxy disks

open access: yes, 2002
We have obtained optical spectra and H I maps for a sample of edge-on spirals. Together with existing photometry, this data allows us to study simultaneously the 3D structure and the kinematics of galaxy disks. This is briefly illustrated for IC 2531.

The Formation of Disk Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1988
In this talk, I will discuss a few particular topics, rather than attempting a general review of the formation of disk galaxies. First recall the basic structure and kinematics of a disk galaxy like the Milky Way. The Table below lists the four main structural components as they are presently understood, and gives typical masses, and (if known) the ...

The relation between bar formation, galaxy luminosity, and environment

open access: yes, 2013
We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy luminosities (or, equivalently, stellar masses).

A Massive Yellow Supergiant in the Far Outer Disk of M31: Evidence for in Situ Massive Star Formation beyond the Optical Radius

open access: yesThe Astronomical Journal
While massive stars are known to shape galactic ecosystems, their formation has long been assumed to require the high-density environments of inner galactic disks. This paradigm is challenged by mounting evidence of young massive stars in extended galaxy

Ages of galaxy bulges and disks from optical and near-infrared colors

open access: yes, 1996
We compare optical and near-infrared colors of disks and bulges in a diameter-limited sample of inclined, bright, nearby, early-type spirals. Color profiles along wedge apertures at 15 degrees from the major axis and on the minor axis on the side of the ...

Emergence of the Galaxy Morphology–Star Formation Activity–Clustercentric Radius Relations in Galaxy Clusters

open access: yesThe Astrophysical Journal
We investigate when and how the relations of galaxy morphology and star-forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy clusters with total mass ${{M}}_{\mathrm{tot}}^{\mathrm{cl}}\gt 5\times {10}^{13}
