Shear, writhe and filaments: turbulence in the high latitude molecular cloud MBM 40

Marco Monaci, Loris Magnani, Steven N. Shore +2

Context. It is almost banal to say that the interstellar medium (ISM) is structurally and thermodynamically complex. But the variety of the governing processes, including stellar f…

Environmental Effects on the Dynamical Evolution of Star Clusters in Turbulent Molecular Clouds

Paolo Suin, Steven N. Shore, Václav Pavlík

Context: Star clusters form within giant molecular clouds that are strongly altered by the feedback action of the massive stars, but the cluster still remains embedded in a dense,…

Structure and Expansion Law of HII Regions in structured Molecular Clouds

Manuel Zamora-Avilés, Enrique Vázquez-Semadeni, Ricardo F. González +6

We present radiation-magnetohydrodynamic simulations aimed at studying evolutionary properties of H\,{\normalsize II} regions in turbulent, magnetised, and collapsing molecular clo…

Periodicity makes galactic shocks unstable - I. Linear analysis

Mattia C. Sormani, Emanuele Sobacchi, Steven N. Shore +2

We study the dynamical stability of stationary galactic spiral shocks. The steady-state equilibrium flow contains a shock of the type derived by Roberts in the tightly wound approx…

Long-term multi-wavelength variability and correlation study of Markarian 421 from 2007 to 2009

MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +176

We study the multi-band variability and correlations of the TeV blazar Mrk 421 on year time scales, which can bring additional insight on the processes responsible for its broadban…

Very-high-energy gamma-rays from the Universe's middle age: detection of the z=0.940 blazar PKS 1441+25 with MAGIC

MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +246

The flat-spectrum radio quasar PKS 1441+25 at a redshift of z = 0.940 is detected between 40 and 250 GeV with a significance of 25.5 σ using the MAGIC telescopes. Together with the…
