Observations of Selected AGN with H.E.S.S.
No full textA sample of selected active galactic nuclei (AGN) was observed in 2003 and 2004 with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging atmospheric-Cherenkov telescopes in Namibia. The redshifts of these candidate very-high-energy (VHE, >100 GeV) γ-ray emitters range from ≉=0.00183 to ≉=0.333. Significant detections were already reported for some of these objects, such as PKS 2155-304 and Mkn421. Marginal evidence (3.1σ) for a signal is found from large-zenith-angle observations of Mkn501, corresponding to an integral flux of I(>1.65 TeV) = (1.5±0.6stat ±0.3syst)x 10-12cm-2s-1 or ~15% of the Crab Nebula flux. Integral flux upper limits for 19 other AGN, based on exposures of ~1 to ~8 hours live time, and with average energy thresholds between 160 GeV and 610 GeV, range from 0.4% to 5.1% of the Crab Nebula flux. All the upper limits are the most constraining ever reported for these objects
The Status and Performance of H.E.S.S.
No full textThe High Energy Stereoscopic System (H.E.S.S.) is an array of four imaging air-Cherenkov telescopes located in the Khomas Highlands of Namibia (23° 16' 18" S, 16° 30' 1" E, 1835 m above sea level). Construction of H.E.S.S. Phase-1 is complete as of December 2003. Although under construction, H.E.S.S. has been operating since June 2002, with observations using increasing numbers of telescopes as they became available. The good angular resolution and background rejection provided by the stereoscopic technique give H.E.S.S. a low energy threshold (~100 GeV)and allows the detection of a 1% Crab flux source in ~25 hours of observation. This sensitivity is unprecedented and has enabled H.E.S.S. to detect numerous new sources of astrophysical gamma-rays. Further details regarding the status and performance of H.E.S.S. are reported here
H.E.S.S. Observations of AGN
No full textThe High Energy Stereoscopic System (H.E.S.S.) is an array of four imaging air-Cherenkov telescopes located in the Khomas Highlands of Namibia (23° 16' 18" S, 16° 30' 1" E, 1800m above sea level). The stereoscopic technique gives H.E.S.S. good angular resolution (99%). These properties coupled with the low energy threshold (~100 GeV)of the detector allows the detection of a 1% Crab flux source in ~25 hours of observation. H.E.S.S. can therefore perform searches for VHE gamma-ray emission from astrophysical objects, such as AGN, with unprecedented sensitivity. The detections by H.E.S.S. of VHE gamma rays from the blazars PKS 2155-304, Mkn 421 and PKS 2005-489 are reported here
The H.E.S.S. Standard Analysis Technique
No full textThe High Energy Stereoscopic System (H.E.S.S.) is an array of four imaging atmospheric Cherenkov telescopes located in Namibia. With the ability to detect a 1 % Crab Nebula flux source in ~25 hours of observation, H.E.S.S. is currently the most sensitive detector of astrophysical VHE (>100GeV) photons. The H.E.S.S. collaboration has published the detection of more than 30 sources of VHE γ-rays, rejecting the large cosmic-ray background, and determining the spectrum and flux of the detected sources is presented

Discovery of VHE Gamma Rays from PKS 2005-489
No full textThe high-frequency peaked BL Lac PKS 2005-489 (≉=0.071) was observed in 2003 and 2004 with the H.E.S.S. stereoscopic array of imaging atmospheric-Cherenkov telescopes in Namibia. A signal was detected at the 6.7σ level in the 2004 observations (24.2 hrs live time), but not in the 2003 data set (27.3 hrs live time).The integral flux above 200 GeV observed in 2004 is (6.9±1.0stat ±1.4syst)x 10-12cm-2s-1, corresponding to ~2.5% of the flux observed from the Crab Nebula. The 99% upper limit on the flux in 2003, I(>200 GeV)-12cm-2s-1, is smaller than the flux measured in 2004, suggesting an increased level of activity in 2004. However, the data show no evidence for significant variability on any time scale less than a year. An energy spectrum is measured and is characterized by a very soft power law (photon index of Γ =4.0±0.4stat)
H.E.S.S. detects historically high fluxes of Very High Energy gamma-rays from PKS 2155-304
No full textWe report on the H.E.S.S. observations of the blazar PKS 2155-304 at VHE gamma-rays (E>200 GeV) varying between ~40 and ~100% of the Crab flux. On the night of 7/24-25 the source was seen in *preliminary* analyses with a significance of 30 sigma/sqrt(hr), or an average 89% of HESS Crab flux above 200 GeV. On the night of 7/25-26 the source was seen with 25 sigma/sqrt(hr) or an average of 62% Crab. On the night of 7/27-28 the source was seen with 14 sigma/sqrt(hr) with a light weather degradation. HESS will monitor PKS 2155-304 until Aug. 03, 2007. Predicted observation windows are listed below, within which RXTE ToO observations are scheduled. Simultaneous observations at all wavelengths are strongly encouraged.

Leading Them to the Promised Land: Woodrow Wilson, Covenant Theology, and the Mexican Revolution, 1913–1915
No full texthttps://kent-islandora.s3.us-east-2.amazonaws.com/new_foreign_relations/1/thumbnail.jpgHow Wilson’s religious heritage shaped his response to the Mexican Revolution
“In Wilson’s view, America had a part to play as a divine instrument. To deny the United States an active role in the world was an attempt to deny God’s will.” —from the Introduction
The First Amendment of the United States Constitution mandates that government and religious institutions remain separate and independent of each other. Yet, the influence of religion on American leaders and their political decisions cannot be refuted.Leading Them to the Promised Land is the first book to look at how Presbyterian Covenant Theology affected U.S. president Woodrow Wilson’s foreign policy during the Mexican Revolution.
The son of a prominent southern minister, Wilson was a devout Presbyterian. Throughout his life he displayed a strong conviction that covenants, or formal promises made binding by an oath to God, should be the basis for human relationships, including those between government and public organizations. This belief is demonstrated in Wilson’s attempt to bring peaceful order to the world with the 1919 Covenant of the League of Nations.
Through careful investigation of Wilson’s writings and correspondence, along with other contemporary sources, author Mark Benbow shows how Wilson’s religious heritage shaped his worldview, including his assumption that nations should come together in a covenant to form a unitary whole like the United States. As a result, Wilson attempted to nurture a democratic state in revolutionary Mexico when rivals Venustiano Carranza and Pancho Villa threatened U.S. interests. His efforts demonstrate the difficulty a leader has in reconciling his personal religious beliefs with his nation’s needs.
Leading Them to the Promised Land adds to the growing body of scholarship in international history that examines the connections between religion and diplomacy. It will appeal to readers interested in the history of U.S. foreign relations and the influence of religion on international politics.</p
