Tev gamma‐ray observations of the perseus and abell 2029 galaxy clusters
(IOP Publishing, 2006-06-10)
Galaxy clusters might be sources of TeV gamma rays emitted by high-energy protons and electrons accelerated by large-scale structure formation shocks, galactic winds, or active galactic nuclei. Furthermore, gamma rays may ...
Geohab–the global ecology and oceanography of harmful algal blooms program: motivation, goals, and legacy
(The Oceanography Society, 2017-03-01)
In 2001, the first international research program focusing exclusively on harmful marine algae, GEOHAB (Global Ecology and Oceanography of Harmful Algal Blooms), was established by the HAB research community, under the ...
Renal function, concomitant medication use and outcomes following acute coronary syndromes
(Oxford University Press (OUP), 2005-07-19)
Background. Chronic kidney disease (CKD) is highly prevalent in patients with cardiovascular disease. We explored the associations of CKD with outcomes using combined data from two large acute coronary syndrome (ACS) trials. ...
Insights into the high-energy γ-ray emission of markarian 501 from extensive multifrequency observations in thefermiera
(IOP Publishing, 2011-01-12)
We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average Large Area Telescope (LAT) gamma-ray spectrum of Mrk 501 can be well described by a single ...
Multi-wavelength observations of the flaring gamma-ray blazar 3c 66a in 2008 october
(IOP Publishing, 2010-12-14)
The BL Lacertae object 3C 66A was detected in a flaring state by the Fermi Large Area Telescope (LAT) and VERITAS in 2008 October. In addition to these gamma-ray observations, F-GAMMA, GASP-WEBT, PAIRITEL, MDM, ATOM, Swift, ...
Fermilarge area telescope observations of markarian 421: the missing piece of its spectral energy distribution
(IOP Publishing, 2011-07-15)
We report on the gamma-ray activity of the high-synchrotron-peaked BL Lacertae object Markarian 421 (Mrk 421) during the first 1.5 years of Fermi operation, from 2008 August 5 to 2010 March 12. We find that the Large Area ...
A strong limit on the very-high-energy emission from grb 150323a
(American Astronomical Society, 2018-04-10)
On 2015 March 23, the Very Energetic Radiation Imaging Telescope Array System (VERITAS) responded to a Swift-Burst Alert Telescope (BAT) detection of a gamma-ray burst, with observations beginning 270 s after the onset of ...
Gamma-rays from the quasar pks 1441+25: story of an escape
(IOP Publishing, 2015-12-15)
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 ...
Multiwavelength observations of the blazar bl lacertae: a new fast tev gamma-ray flare
(American Astronomical Society, 2018-03-28)
Combined with measurements made by very-long-baseline interferometry, the observations of fast TeV gamma-ray flares probe the structure and emission mechanism of blazar jets. However, only a handful of such flares have ...
Identification of broadly neutralizing antibody epitopes in the hiv-1 envelope glycoprotein using evolutionary models
(Springer Nature, 2013-01-01)
Background: Identification of the epitopes targeted by antibodies that can neutralize diverse HIV-1 strains can provide important clues for the design of a preventative vaccine.
Methods: We have developed a computational ...
