Markarian 421 (Mrk 421 hereafter) is a nearby active galaxy with a featureless optical spectrum
devoid of prominent emission or absorption lines, strongly polarized variable optical and …

The high-frequency-peaked BL Lacertae object 1ES 0229+ 200 is a relatively distant (z=
0.1396), hard-spectrum (Γ∼ 2.5), very-high-energy (VHE; E> 100 GeV) emitting γ-ray blazar. …

TeV J2032+ 4130 was the first unidentified source discovered at very high energies (VHEs;
E> 100 GeV), with no obvious counterpart in any other wavelength. It is also the first …

We present very high energy (VHE) imaging of MGRO J2019+ 37 obtained with the VERITAS
observatory. The bright extended (∼ 2) unidentified Milagro source is located toward the …

The very-high-energy (VHE; E> 100 GeV) gamma-ray source HESS J0632+ 057 is a new
member of the elusive class of gamma-ray binaries (Aharonian et al. 2007; Hinton et al. 2009; …

We present deep VERITAS observations of the blazar PKS 1424+ 240, along with
contemporaneous Fermi Large Area Telescope, Swift X-ray Telescope, and Swift UV Optical …

During moonlit nights, observations with ground-based Cherenkov telescopes at very high
energies (VHEs, $ E\gt 100$ GeV) are constrained since the photomultiplier tubes (PMTs) in …

We report on multifrequency observations performed during 2012 December–2013 August of
the first narrow-line Seyfert 1 galaxy detected in γ-rays, PMN J0948+0022 (z = 0.5846). A γ-…

We report on deep observations of the extended TeV gamma-ray source MGRO J1908+ 06
made with the VERITAS very high energy gamma-ray observatory. Previously, the TeV …

… has been a consistent finding in fMRI studies of preterm and low birth weight groups, including
one study using the same fMRI paradigm as the one used in the current study (Griffiths et …
