Spectroscopy and chemical synthesis of interstellar ice analogues [PDF]
, 2014 Molecular synthesis and chemical evolution in the interstellar medium has been studied under laboratory conditions. The method of preparation and energetic processing of interstellar ice analogues on surfaces, spectroscopic principles for monitoring chemistry and morphology of these ice analogues and analysis methodologies are discussed in detail.

VLT Spectroscopy of Blue Supergiants in IC 1613 [PDF]
The Astrophysical Journal, 2007 We present multi-object spectroscopy of young, massive stars in the Local Group galaxy IC 1613. We provide the spectral classification and a detailed spectral catalog for 54 OBA stars in this galaxy. The majority of the photometrically selected sample is composed of B- and A-type supergiants. The remaining stars include early O-type dwarfs and the only

Infrared Spectroscopy and Photochemistry of Anthracoronene in Cosmic Water Ice [PDF]
ACS Earth and Space Chemistry, 2022 We present a laboratory study of the polycyclic aromatic hydrocarbon (PAH) anthracoronene (AntCor, C36H18) in simulated interstellar ices in order to determine its possible contribution to the broad infrared absorption bands in the 5-8 μm wavelength interval.

Development of a Bioaerosol single particle detector (BIO IN) for the Fast Ice Nucleus CHamber FINCH [PDF]
, 2010 In this work we present the setup and first tests of our new BIO IN detector. This detector was constructed to classify atmospheric ice nuclei (IN) for their biological content. It is designed to be coupled to the Fast Ice Nucleus CHamber FINCH.

Fluctuation spectroscopy of surface melting of ice with and without impurities [PDF]
Physical Review E, 2019 Water, in its three phases, is ubiquitous, and the surface properties of ice is important to clarifying the process of melting, as well as to various other fields, including geophysics. As such, the subject has been studied both theoretically and experimentally, for over a hundred years, while being an active field of research today.
