Planck far-infrared detection of hyper suprime-cam protoclusters at z similar to 4: Hidden AGN and star formation activi...
...
We perform a stacking analysis of Planck, AKARI, Infrared Astronomical Satellite, Wide-field Infrared Survey Explorer, and Herschel images of the largest number of (candidate) protoclusters at z ~ 3.8 selected from the Hyper Suprime-Cam Subaru Strategic Program. Stacking the images of the 179 candidate protoclusters, the combined infrared (IR) emis...
A catalogue of galactic supernova remnants in the far-infrared : revealing ejecta dust in pulsar wind nebulae
...
We search for far-infrared (FIR) counterparts of known supernova remnants (SNRs) in the Galactic plane (10 deg
Entropy of plasmas described with regularized kappa distributions
© 2018 American Physical Society. In classical thermodynamics the entropy is an extensive quantity, i.e., the sum of the entropies of two subsystems in equilibrium with each other is equal to the entropy of the full system consisting of the two subsystems. The extensitivity of entropy has been questioned in the context of a theoretical foundation f...

Stellar population of the superbubble N206 in the LMC II. Parameters of the OB and WR stars, and the total massive star ...
© ESO 2018 Context. Clusters or associations of early-type stars are often associated with a “superbubble” of hot gas. The formation of such superbubbles is caused by the feedback from massive stars. The complex N 206 in the Large Magellanic Cloud (LMC) exhibits a superbubble and a rich massive star population. Aims. Our goal is to perform quantita...
Temporal feedback control of high-intensity laser pulses to optimize ultrafast heating of atomic clusters
...
We describe how active feedback routines can be applied at limited repetition rate (5 Hz) to optimize high- power ( P> 10 TW) laser interactions with clustered gases. Optimization of x-ray production from an argon cluster jet, using a genetic algorithm, approximately doubled the measured energy through temporal modification of the 150 mJ driving la...
A Space-based Observational Strategy for Characterizing the First Stars and Galaxies Using the Redshifted 21cm Global Sp...
...
The redshifted 21 cm monopole is expected to be a powerful probe of the epoch of the first stars and galaxies ($10\lt z\lt 35$). The global 21 cm signal is sensitive to the thermal and ionization state of hydrogen gas and thus provides a tracer of sources of energetic photons—primarily hot stars and accreting black holes—which ionize and heat the h...

NuStar observations of WISE J1036+0449, a galaxy at z ∼ 1 obscured by hot dust
...
Hot dust-obscured galaxies (hot DOGs), selected from Wide-Field Infrared Survey Explorer’s all-sky infrared survey, host some of the most powerful active galactic nuclei known and may represent an important stage in the evolution of galaxies. Most known hot DOGs are located at z> 1.5, due in part to a strong bias against identifying them at lower r...
