Aims: Our goal is to study the chemical composition of the outflows of active galactic nuclei and starburst galaxies. Methods: We obtained high-resolution interferometric observati…
Tester Interactivity makes a Difference in Search-Based Software Testing: A Controlled Experiment
Bogdan Marculescu, Simon Poulding, Robert Feldt +2
Context: Search-based software testing promises to provide users with the ability to generate high-quality test cases, and hence increase product quality, with a minimal increase i…
Symmetry reduction for central force problems
Robert I McLachlan, Klas Modin, Olivier Verdier
We given an elementary illustration of symmetry reduction for central force problems, drawing phase portraits of the reduced dynamics as the intersection of Casimir and energy leve…
Disk Dispersal: Theoretical Understanding and Observational Constraints
U. Gorti, R. Liseau, Zs. Sandor +1
Protoplanetary disks dissipate rapidly after the central star forms, on time-scales comparable to those inferred for planet formation. In order to allow the formation of planets, d…
The XXL Survey XI: ATCA 2.1 GHz continuum observations
Vernesa Smolcic, Jacinta Delhaize, Minh Huynh +16
We present 2.1 GHz imaging with the Australia Telescope Compact Array (ATCA) of a 6.5 deg^2 region within the XXM-Newton XXL South field using a band of 1.1-3.1 GHz. We achieve an…
The XXL Survey: I. Scientific motivations - XMM-Newton observing plan - Follow-up observations and simulation programme
M. Pierre, F. Pacaud, C. Adami +89
We present the XXL Survey, the largest XMM programme totaling some 6.9 Ms to date and involving an international consortium of roughly 100 members. The XXL Survey covers two extrag…
The XXL Survey. II. The bright cluster sample: catalogue and luminosity function
F. Pacaud, N. Clerc, P. A. Giles +40
Context. The XXL Survey is the largest survey carried out by the XMM-Newton satellite and covers a total area of 50 square degrees distributed over two fields. It primarily aims at…
The Globalization of Academic Entrepreneurship? The Recent Growth (2009-2014) in University Patenting Decomposed
Loet Leydesdorff, Henry Etzkowitz, Duncan Kushnir
The contribution of academia to US patents has become increasingly global. Following a pause, with a relatively flat rate, from 1998 to 2008, the long-term trend of university pate…
Ortho-to-para ratio of NH2. Herschel-HIFI observations of ortho- and para-NH2 rotational transitions towards W31C, W49N, W51 and G34.3+0.1
C. M. Persson, A. O. H. Olofsson, R. Le Gal +10
We have used the Herschel-HIFI instrument to observe both nuclear spin symmetries of amidogen (NH2) towards the high-mass star-forming regions W31C (G10.6-0.4), W49N (G43.2-0.1), W…
