Detection of two power-law tails in the probability distribution functions of massive GMCs [PDF]

, 2015
We report the novel detection of complex high-column density tails in the probability distribution functions (PDFs) for three high-mass star-forming regions (CepOB3, MonR2, NGC6334), obtained from dust emission observed with Herschel.

Multi-epoch, high spatial resolution observations of multiple T Tauri systems [PDF]

, 2017
Context. In multiple pre-main-sequence systems the lifetime of circumstellar disks appears to be shorter than around single stars, and the actual dissipation process may depend on the binary parameters of the systems. Aims.

Decade‐long X‐ray observations of HESS J0632+057

Astronomische Nachrichten, Volume 340, Issue 6, Page 465-474, July 2019., 2019
Abstract We present the results of a decade of X‐ray observations of the gamma ray loud binary HESS J0632+057 and interpret the available broadband data in view of the system geometry and emission mechanisms. We have performed an analysis of all X‐ray data available to date from Swift, XMM‐Newton, Chandra, NuSTAR, and Suzaku.

Impact of Cosmic‐Ray Physics on Dark Matter Indirect Searches

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
The quest for the elusive dark matter (DM) that permeates the Universe (and in general the search for signatures of physics beyond the Standard Model at astronomical scales) provides a unique opportunity and a tough challenge to the high energy astrophysics community.
