Understanding the extreme luminosity of DES14X2fna
We present DES14X2fna, a high-luminosity, fast-declining Type IIb supernova (SN IIb) at redshift z = 0.0453, detected by the Dark Energy Survey (DES)...
Understanding the thermal and magnetic properties of an X-class flare in the low solar atmosphere
We analyse the spatial distribution and vertical stratification of the physical parameters of the solar atmosphere when an X-class flare occurs. We made use of...
Unexplored outflows in nearby low luminosity AGNs. The case of NGC 1052
Context. Multi-phase outflows play a central role in galaxy evolution shaping the properties of galaxies. Understanding outflows and their effects in low...
Unfolding of differential energy spectra in the MAGIC experiment
The paper describes the different methods, used in the MAGIC experiment, to unfold experimental energy distributions of cosmic ray particles (γ-rays). Questions...
Unidentified quasars among stationary objects from Gaia DR2
Here we apply a technique selecting quasar candidates purely as sources with zero proper motions in the Gaia data release 2 (DR2). We demonstrate that this...
Unifying A Boxy Bulge and Planar Long Bar in the Milky Way
It has been known for sometime that the Milky Way is a barred disk galaxy. More recently several studies inferred from star count observations that the Galaxy...
UNIT project: Universe N-body simulations for the Investigation of Theoretical models from galaxy surveys
We present the UNIT N-body cosmological simulations project, designed to provide precise predictions for non-linear statistics of the galaxy distribution. We...
Unitarization of infinite-range forces: graviton-graviton scattering
A method to unitarize the scattering amplitude produced by infinite-range forces is developed and applied to Born terms. In order to apply S-matrix techniques...
UNITSIM-Galaxies: data release and clustering of emission-line galaxies
New surveys such as European Space Agencys (ESA's) Euclid mission are planned to map with unprecedented precision the large-scale structure of the Universe by...
