Almost all are new discoveries and about 50% are YSOs. This provides further evidence that YSOs are the commonest high amplitude infrared variable stars in the Galactic plane. In the 2010-2014 time series of likely YSOs we find that the amplitude of variability increases towards younger evolutionary classes (class I and flat-spectrum sources) except on short timescales (<25 days) where this trend is reversed. -

BYURAKAN ASTROPHYSICAL OBSERVATORY in 2010: ANNUAL REPORT
BYURAKAN ASTROPHYSICAL OBSERVATORY in 2010: ANNUAL REPORT Introduction In 2010 we had ups and downs in the Byurakan observatory. We would like to mention that a small group of students started very serious activities in modernization of 1m Schmidt camera. All the engineering works are completed and in a few months this telescope will be controllable after more than 20 years of its stoppage. Unfortunately during 2010 we could not begin the installation of the aluminization plant and the 2.6m telescope continued its work with the main mirror which desperately needs a renovated aluminum surface. Moreover the main telescope of the observatory needs a cardinal renewal of the control system as far as the elemental base is designed on the basis of the 60s of the last century, which should be substituted with new ones. This is one of the most important works to be done in the nearest future. As the most prominent event of the year 2010 for the BAO one should mention the third Byurakan International School for young astronomers organized jointly with the IAU. The Byurakan schools evidently became traditional and every year the number of applications increases. This is one of the most welcome tendencies we observed in 2010. In 2010 at last the book “Evolution of cosmic objects through their physical activity” was published presenting the proceedings of the international conference devoted to the 100th anniversary of Viktor Ambartsumian (Editors: H.A. Harutyunian, A.M. Mickaelian & Y. Terzian). Some international projects are initiated, which seems to be very promising but which slowed down and did not begin in the last year as we planned (especially the Italian-Armenian collaboration project). -

Binocular Challenges
This page intentionally left blank Cosmic Challenge Listing more than 500 sky targets, both near and far, in 187 challenges, this observing guide will test novice astronomers and advanced veterans alike. Its unique mix of Solar System and deep-sky targets will have observers hunting for the Apollo lunar landing sites, searching for satellites orbiting the outermost planets, and exploring hundreds of star clusters, nebulae, distant galaxies, and quasars. Each target object is accompanied by a rating indicating how difficult the object is to find, an in-depth visual description, an illustration showing how the object realistically looks, and a detailed finder chart to help you find each challenge quickly and effectively. The guide introduces objects often overlooked in other observing guides and features targets visible in a variety of conditions, from the inner city to the dark countryside. Challenges are provided for viewing by the naked eye, through binoculars, to the largest backyard telescopes. Philip S. Harrington is the author of eight previous books for the amateur astronomer, including Touring the Universe through Binoculars, Star Ware, and Star Watch. He is also a contributing editor for Astronomy magazine, where he has authored the magazine’s monthly “Binocular Universe” column and “Phil Harrington’s Challenge Objects,” a quarterly online column on Astronomy.com. He is an Adjunct Professor at Dowling College and Suffolk County Community College, New York, where he teaches courses in stellar and planetary astronomy.

Supernova Remnants Observed by the Fermi Large Area Telescope: the Case of HB 21
Sede Amministrativa: Universit`adegli Studi di Padova Dipartimento di Fisica e Astronomia SCUOLA DI DOTTORATO DI RICERCA IN FISICA CICLO XXVI Supernova remnants observed by the Fermi Large Area Telescope: the case of HB 21 Direttore della Scuola: Prof. Andrea VITTURI Supervisore: Dott.Denis BASTIERI Dott. Luigi TIBALDO Dottorando: Giovanna PIVATO ii Preprint January 29, 2014 To my father Ugo iv v Abstract Since their discovery, cosmic rays (CRs) are one of the most studied phe- nomena in the Universe. The origin of the spectrum, which extends for more than 12 orders of magnitude, is still debated. Up to ∼ 1015 eV, CRs are accelerated in the Galaxy, and Supernova Remnants (SNRs) are the most likely candidates to accelerate them. If an expanding SNR interacts with molecular clouds, particles accelerated in the expanding shock can produce high-energy photons, the observation of which can provide valuable infor- mation about the accelerated particles population. Of particular interest are combined γ-ray and radio observations: accelerated particles emit ra- dio waves via synchrotron emission and γ rays via bremsstrahlung, inverse Compton and nucleon-nucleon interaction. Thanks to its unprecedent angular resolution and sensitivity, the Fermi Gamma-ray Space Telescope is the γ-ray detector ideal for the study of ex- tended structures in the Galaxy. We present the analysis of Fermi Large Area Telescope γ-ray observations of HB 21 (G89.0+4.7). We detected significant γ-ray emission associated with the remnant: the flux above 100 MeV is 9:4 ± 0:8(stat) ± 1:6(syst) × 1011 erg cm2 s−1.
