Development of astrochemical and radiative transfer codes

  • Post author:Thomas Bisbas
  • Post published:January 20, 2023
  • Post category:Research projects
  • Post comments:0 Comments

Photodissociation regions (PDRs) are ubiquitously present in the interstellar medium (ISM) and consist of predominantly neutral gas and dust illuminated by far-ultraviolet (FUV) radiation (6 < hv < 13.6 eV).…

Determining the PDR properties using probability density functions

  • Post author:Thomas Bisbas
  • Post published:January 19, 2023
  • Post category:Research projects
  • Post comments:0 Comments

Determining the photodissociation region (PDR) properties of the interstellar medium (ISM), such as the atomic and molecular mass content, is of fundamental importance to understand the star-formation process. The advent…

Photodissociation region diagnostics

  • Post author:Thomas Bisbas
  • Post published:January 18, 2023
  • Post category:Research projects

To determine the physical properties and evolution of the interstellar medium (ISM), we need to model its chemical conditions, since these help set its heating & cooling rates and ionization…

Cosmic-ray induced destruction of CO

  • Post author:Thomas Bisbas
  • Post published:January 17, 2023
  • Post category:Research projects
  • Post comments:0 Comments

Cosmic-rays are relativistic charged particles (and not "rays" in terms of electromagnetic radiation) and play an important role in regulating the chemistry at high column densities. These high column-densities are…

Origin of the [CII]-deficit

  • Post author:Thomas Bisbas
  • Post published:January 16, 2023
  • Post category:Research projects

The line of ionized carbon at 158μm, denoted as [CII], is one of the brightest lines originating from star-forming galaxies. Under typical environmental conditions of the interstellar medium (ISM), the…

Expansion of HII-regions

  • Post author:Thomas Bisbas
  • Post published:January 15, 2023
  • Post category:Research projects

Massive stars emit copious amount of photons that are able to ionize the atom of hydrogen in their nearby environment of the interstellar medium (ISM). This influence of UV radiation…

Fine-structure lines as diagnostic for cloud-cloud collision activity

  • Post author:Thomas Bisbas
  • Post published:January 15, 2023
  • Post category:Research projects
  • Post comments:0 Comments

The dominant process for the galactic star formation is believed to be the collision between giant molecular clouds. The collision triggers the gravitational collapse of the merged clouds, creating star…
