Chemistry and ro-vibrational excitation of CH in the planetary nebula NGC 7027
Milan Sil, Alexandre Faure, Helmut Wiesemeyer +5
Small carbon hydride cations, such as the methylidyne ion (CH), play an important role in the chemistry of the interstellar medium (ISM). They participate in gas-phase reaction…
Binding energy distributions of alcohols, thiols, and their precursors on interstellar water ice surfaces
Arghyadeb Roy, Ankan Das, Milan Sil +4
Binding energy (BE) is a critical parameter in astrochemical modeling, governing the retention of species on interstellar dust grains and their subsequent chemical evolution. Howev…
Metallic species in interstellar medium: Astrochemical modeling
Ankan Das, Milan Sil, Paola Caselli
Metal-bearing species in diffuse or molecular clouds are often overlooked in astrochemical modeling except for the charge exchange process. However, catalytic cycles involving thes…
Chemistry and ro-vibrational excitation of HeH in the Planetary Nebula NGC 7027
Milan Sil, Alexandre Faure, Helmut Wiesemeyer +5
HeH belongs to the class of "reactive" ions that can be destroyed so quickly that chemical formation and destruction rates may compete with inelastic rates and should be consid…
Fate and detectability of rare gas hydride ions in nova ejecta: A case study with nova templates
Milan Sil, Ankan Das, Ramkrishna Das +6
HeH was the first heteronuclear molecule to form in the metal-free Universe after the Big Bang. The molecule gained significant attention following its first circumstellar dete…
Assessing realistic binding energies of some essential interstellar radicals with amorphous solid water. A fully quantum chemical approach
Milan Sil, Arghyadeb Roy, Prasanta Gorai +6
In the absence of laboratory data, state-of-the-art quantum chemical approaches can provide estimates of the binding energy (BE) of interstellar species with grains. Without BE val…
Physics And Chemistry Of Star Forming Region And Protoplanetary Disk
Milan Sil
My thesis work aims to study the inter-relation between various physical and chemical conditions in a wide range of astrophysical environments. Our studied regions range from the s…
Astrochemical model to study the abundances of branched carbon-chain molecules in a hot molecular core with realistic binding energies
Satyam Srivastav, Milan Sil, Prasanta Gorai +3
Straight-chain (normal-propyl cyanide, n - C3H7CN) and branched-chain (iso-propyl cyanide, i - C3H7CN) alkyl cyanides are recently identified in the massive star-forming regions (S…
Is there any linkage between interstellar aldehyde and alcohol?
Suman Kumar Mondal, Prasanta Gorai, Milan Sil +8
It is speculated that there might be some linkage between interstellar aldehydes and their corresponding alcohols. Here, an observational study and astrochemical modeling are coupl…
Chemical complexity of phosphorous bearing species in various regions of the Interstellar medium
Milan Sil, Satyam Srivastav, Bratati Bhat +10
Phosphorus related species are not known to be as omnipresent in space as hydrogen, carbon, nitrogen, oxygen, and sulfur-bearing species. Astronomers spotted very few P-bearing mol…
Effect of binding energies on the encounter desorption
Ankan Das, Milan Sil, Rana Ghosh +4
The abundance of interstellar ice constituents is usually expressed with respect to the water ice because, in denser regions, a significant portion of the interstellar grain surfac…
Exploring the Possibility of Identifying Hydride and Hydroxyl Cations of Noble Gas Species in the Crab Nebula Filament
Ankan Das, Milan Sil, Bratati Bhat +3
The first identification of the argonium ion (ArH+) towards the Crab Nebula supernova remnant was proclaimed by the Herschel in the sub-millimeter and far-infrared domain. Very rec…
A Systematic Study on the Absorption Features of Interstellar Ices in Presence of Impurities
Prasanta Gorai, Milan Sil, Ankan Das +12
Spectroscopic studies play a key role in the identification and analysis of interstellar ices and their structure. Some molecules have been identified within the interstellar ices…
Identification of pre-biotic molecules containing Peptide-like bond in a hot molecular core, G10.47+0.03
Prasanta Gorai, Bratati Bhat, Milan Sil +4
After hydrogen, oxygen, and carbon, nitrogen is one of the most chemically active species in the interstellar medium (ISM). Nitrogen bearing molecules have great importance as they…
An Approach to Estimate the Binding energy of Interstellar Species
Ankan Das, Milan Sil, Prasanta Gorai +2
One of the major obstacles to accurately model the interstellar chemistry is an inadequate knowledge about the binding energy (BE) of interstellar species with dust grains. In dens…
Chemical modeling for predicting the abundances of certain aldimines and amines in hot cores
Milan Sil, Prasanta Gorai, Ankan Das +3
We consider six isomeric groups (CH3N, CH5N, C2H5N, C2H7N, C3H7N and C3H9N) to review the presence of amines and aldimines within the interstellar medium (ISM). Each of these group…
