Hydrodynamic Modeling of the Interaction of Winds within a Collapsing Turbulent Gas Cloud

open access: yesAdvances in Astronomy, 2015
By using the particle-based code Gadget2, we follow the evolution of a gas giant molecular cloud, in which a set of gas particles representing the wind are created by a Monte Carlo scheme and suddenly move outwards from the cloud’s center.

Galactic Cosmic Ray Interaction with the Perseus Giant Molecular Cloud Using Geant4 Monte Carlo Simulation

open access: yesUniverse
Galactic cosmic rays (GCRs), composed of protons and atomic nuclei, are accelerated in sources such as supernova remnants and pulsar wind nebulae, reaching energies up to the PeV range.

Cloud Collision Signatures in the Central Molecular Zone

open access: yesThe Open Journal of Astrophysics
Molecular cloud collisions are a prominent theory for the formation of stars. Observational studies into cloud collisions identify the collision via a bridging feature: a continuous strip of line emission that connects two intensity peaks that are ...

Cloud–Cloud Collision and Cluster Formation in the W5-NW Complex

open access: yesThe Astronomical Journal
We present a detailed structural and gas kinematic study of the star-forming complex W5-NW. A cloud–cloud collision scenario unravels with evidence of collision-induced star and cluster formation.

Star formation in the high-extinction Planck cold clump PGCC G120.69+2.66

open access: yesThe Open Journal of Astrophysics
We investigate the star formation occurring in the Planck Galactic cold clump PGCC 120.69+2.66. Near-infrared JHKs images and K-band spectroscopy obtained with NOTCam at the Nordic Optical Telescope complemented with archive data are used to study the ...
