We present simulations of the multi-phase interstellar medium (ISM) at solar neighbourhood conditions including thermal and non-thermal ISM processes, star cluster formation, feedback from massive stars: stellar winds, hydrogen ionising radiation computed with novel TreeRay radiative transfer method, supernovae (SN), injection cosmic rays (CR). N-body dynamics is a 4th-order Hermite integrator....

We model how the mid-infrared colors of Young Stellar Objects (YSOs) vary with stellar temperature. The spectral energy distribution (SED) of each object has contributions from thermal emission of circumstellar dust, from direct stellar photospheric emission, and from scattered stellar emission. We first isolate the effects of stellar contributions (direct+scattered) to the SED using homologous...

Several authors have suggested the possibility of utilizing measurements of spectrally resolved outgoing longwave radiation (OLR) to monitor the climatic state (e.g. Goody et al., 1998). The idea is attractive since even a moderate degree of spectral resolution allows the assignation of changes seen in the OLR to a particular cause. However, its practical implementation has been hampered by a l...

In the field of gamma-rays Astrophysics in the – energy domain, the understanding of spectra of detected gamma rays is necessary in developing models for acceleration, emission, absorption and propagation of very high energy particles in their sources and in space. Therefore, high precision in the measurement of the energy of observed gammas is important. On the example of the 17 ø MAGIC telesc...

The study of shell-type supernova remnants is a key science focus for the VERITAS TeV telescope array. Supernova remnants (SNRs) are widely considered to be the strongest candidate for the source of cosmic rays below the knee around 10 eV. This presentation will highlight new VERITAS results including new measurements of the spectra of Cas A and IC 443. These results and their implications for ...
