Novel approach for label free super-resolution imaging in far field
(Nature Publishing Group, 2015)
Progress in the emerging areas of science and technology, such as bio- and nano-technologies,
depends on development of corresponding techniques for imaging and probing the structures with
high resolution. Recently, the ...
Multiwavelength observations of Mrk 501 in 2008
(EDP Sciences, 2015-12-17)
Context. Blazars are variable sources on various timescales over a broad energy range spanning from radio to very high energy (>100 GeV, hereafter VHE). Mrk 501 is one of the brightest blazars at TeV energies and has been ...
FirstNuSTAR observations of MRK 501 within a radio to TeV multi-instrument campaign
(IOP Publishing, 2015-10-10)
We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 2013 April
1 and August 10, including the first detailed characterization of the synchrotron peak with Swift and NuSTAR.
During ...
Performance analysis of cone detection algorithms
(Optical Society of America, 2015-04-01)
Many algorithms have been proposed to help clinicians evaluate cone density and spacing, as these may be
related to the onset of retinal diseases. However, there has been no rigorous comparison of the performance
of these ...
Unprecedented study of the broadband emission of Mrk 421 during flaring activity in March 2010
(EDP Sciences, 2015-05-27)
Context. Because of its proximity, Mrk 421 is one of the best sources on which to study the nature of BL Lac objects. Its proximity allows us to characterize its broadband spectral energy distribution (SED).
Aims. The ...
The most powerful flaring activity from the NLSyl PMN J0948+0022
(Oxford University Press, 2015-01-21)
We report on multifrequency observations performed during 2012 December-2013 August of the first narrow-line Seyfert 1 galaxy detected in gamma-rays, PMN J0948+0022 (z = 0.5846). A y -ray flare was observed by the Large ...
Gamma-rays from the quasar PKS 1441+25: story of an escape
(2015-12-20)
Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the universe. The detection of significant emission above 100 ...
A search for pulsations from Geminga above 100 GeV with VERITAS
(American Astronomical Society, 2015-02-10)
We present the results of 71.6 hr of observations of the Geminga pulsar (PSR J0633+1746) with the VERITAS very-high-energy gamma-ray telescope array. Data taken with VERITAS between 2007 November and 2013 February were ...
VERITAS observations of the BL Lac object PG 1553+113
(American Astronomical Society, 2015-01-20)
We present results from VERITAS observations of the BL Lac object PG 1553+113 spanning the years 2010, 2011, and 2012. The time-averaged spectrum, measured between 160 and 560 GeV, is well described by a power law with a ...
VLT polarimetry observations of the middle-aged pulsar PSR B0656+14
(EDP Sciences, 2015-11-02)
Context. Optical polarisation measurements are key tests for different models of the pulsar magnetosphere. Furthermore, comparing the relative orientation of the phase-averaged linear polarisation direction and the pulsar ...
