Planck 2013 results. XIII. Galactic CO emission

Xin Chen, Julien Lesgourgues

Rotational transition lines of CO play a major role in molecular radio astronomy as a mass tracer and in particular in the study of star formation and Galactic structure. Although a wealth of data exists for the Galactic plane and some well-known molecular ...

MAGIC reveals a complex morphology within the unidentified gamma-ray source HESS J1857+026

Thomas Günther Bretz

Aims. HESS J1857+026 is an extended TeV gamma-ray source that was discovered by H. E. S. S. as part of its Galactic plane survey. Given its broadband spectral energy distribution and its spatial coincidence with the young energetic pulsar PSR J1856+0245, t ...

Planck 2013 results. XI. All-sky model of thermal dust emission

Julien Lesgourgues

This paper presents an all-sky model of dust emission from the Planck 353, 545, and 857 GHz, and IRAS 100 mu m data. Using a modified blackbody fit to the data we present all-sky maps of the dust optical depth, temperature, and spectral index over the 353- ...

Ab initio-driven trajectory-based nuclear quantum dynamics in phase space

Ivano Tavernelli

We derive a Bohmian trajectory-based quantum dynamics approach for the calculation of adiabatic and nonadiabatic quantum effects in ab initio on-the-fly molecular dynamics simulations. The method is designed for calculations in the full, unconstrained, pha ...

Identifying clusters as low-lying minima - Efficiency of stochastic and genetic algorithms using inexpensive electronic structure levels

Anne-Clémence Corminboeuf, Fabrice Avaltroni

Molecular candidates possessing unconventional chemical bonding paradigms (e.g., boron wheels, molecular stars, and multicenter bonding) have attracted a great deal of attention by the computational community. The viability of such systems is necessarily a ...

A very extended molecular web around NGC 1275

Yves Revaz

We present the first detection of CO emission lines in the Ha filaments at distances as far as 50 kpc from the centre of the galaxy NGC 1275. This gas is probably dense (>= 10(3) cm(-3)). However, it is not possible to accurately determine the density and ...

Population-specific expression analysis (PSEA) reveals molecular changes in diseased brain

Human diseases are often accompanied by histological changes that confound interpretation of molecular analyses and identification of disease-related effects. We developed population-specific expression analysis (PSEA), a computational method of analyzing ...

Observations of CO in the eastern filaments of NGC 1275

Yves Revaz

We recently found extended CO(2-1) emission from cold molecular gas embedded in the network of Ha filaments surrounding the galaxy NGC 1275 (Salome et al. 2006). We now present CO(2-1) interferometer maps of the eastern filaments, at high spatial and spect ...

Cold gas in the Perseus cluster core: excitation of molecular gas in filaments

Yves Revaz

We have recently detected CO lines in the well-known filaments around NGC 1275, the galaxy at the centre of the Perseus cluster of galaxies. These previous observations, with the HERA multi-beam array at the IRAM 30 m telescope enabled us to make a large m ...
