Abramowski A, Acero F, Aharonian F, Akhperjanian A, Anton G, Barnacka A, et al.
Phys Rev Lett . 2011 May; 106(16):161301. PMID: 21599352
A search for a very-high-energy (VHE; ≥100  GeV) γ-ray signal from self-annihilating particle dark matter (DM) is performed towards a region of projected distance r∼45-150  pc from the Galactic center....

Acero F, Aharonian F, Akhperjanian A, Anton G, Barres de Almeida U, Bazer-Bachi A, et al.
Science . 2009 Sep; 326(5956):1080-2. PMID: 19779150
Starburst galaxies exhibit in their central regions a highly increased rate of supernovae, the remnants of which are thought to accelerate energetic cosmic rays up to energies of approximately 10(15)...

Acciari V, Aliu E, Arlen T, Bautista M, Beilicke M, Benbow W, et al.
Science . 2009 Jul; 325(5939):444-8. PMID: 19574351
The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particles to...

Aharonian F, Akhperjanian A, Barres de Almeida U, Bazer-Bachi A, Becherini Y, Behera B, et al.
Phys Rev Lett . 2009 May; 101(26):261104. PMID: 19437632
The very large collection area of ground-based gamma-ray telescopes gives them a substantial advantage over balloon or satellite based instruments in the detection of very-high-energy (>600 GeV) cosmic-ray electrons. Here...

Aharonian F, Akhperjanian A, Barres de Almeida U, Bazer-Bachi A, Becherini Y, Behera B, et al.
Phys Rev Lett . 2008 Nov; 101(17):170402. PMID: 18999724
In the past few decades, several models have predicted an energy dependence of the speed of light in the context of quantum gravity. For cosmological sources such as active galaxies,...

Phys Rev Lett . 2006 Dec; 97(22):221102. PMID: 17155788
The detection of gamma rays from the source HESS J1745-290 in the Galactic Center (GC) region with the High Energy Spectroscopic System (HESS) array of Cherenkov telescopes in 2004 is...

Science . 2006 Oct; 314(5804):1424-7. PMID: 17068224
The detection of fast variations of the tera-electron volt (TeV) (10(12) eV) gamma-ray flux, on time scales of days, from the nearby radio galaxy M87 is reported. These variations are...

Nature . 2006 Feb; 439(7077):695-8. PMID: 16467831
The source of Galactic cosmic rays (with energies up to 10(15) eV) remains unclear, although it is widely believed that they originate in the shock waves of expanding supernova remnants....

Science . 2005 Jul; 309(5735):746-9. PMID: 16002580
X-ray binaries are composed of a normal star in orbit around a neutron star or stellar-mass black hole. Radio and x-ray observations have led to the presumption that some x-ray...
