Nustar Unveils a Heavily Obscured Low-Luminosity Active Galactic Nucleus in the Luminous Infrared Galaxy Ngc 6286 C
Draft version October 26, 2015 A Preprint typeset using LTEX style emulateapj v. 04/17/13 NUSTAR UNVEILS A HEAVILY OBSCURED LOW-LUMINOSITY ACTIVE GALACTIC NUCLEUS IN THE LUMINOUS INFRARED GALAXY NGC 6286 C. Ricci1,2,*, et al. Draft version October 26, 2015 ABSTRACT We report on the detection of a heavily obscured Active Galactic Nucleus (AGN) in the Lumi- nous Infrared Galaxy (LIRG) NGC 6286, obtained thanks to a 17.5 ks NuSTAR observation of the source, part of our ongoing NuSTAR campaign aimed at observing local U/LIRGs in different merger stages. NGC6286 is clearly detected above 10keV and, by including the quasi-simultaneous Swift/XRT and archival XMM-Newton and Chandra data, we find that the source is heavily obscured 24 −2 [N H ≃ (0.95 − 1.32) × 10 cm ], with a column density consistent with being mildly Compton- −2 thick [CT, log(N H/cm ) ≥ 24]. The AGN in NGC 6286 has a low absorption-corrected luminosity 41 −1 (L2−10 keV ∼ 3 − 20 × 10 ergs ) and contributes .1% to the energetics of the system. Because of its low-luminosity, previous observations carried out in the soft X-ray band (< 10 keV) and in the in- frared excluded the presence of a buried AGN. NGC 6286 has multi-wavelength characteristics typical of objects with the same infrared luminosity and in the same merger stage, which might imply that there is a significant population of obscured low-luminosity AGN in LIRGs that can only be detected by sensitive hard X-ray observations. 1.

Introduction to Astronomical Photometry, Second Edition
This page intentionally left blank Introduction to Astronomical Photometry, Second Edition Completely updated, this Second Edition gives a broad review of astronomical photometry to provide an understanding of astrophysics from a data-based perspective. It explains the underlying principles of the instruments used, and the applications and inferences derived from measurements. Each chapter has been fully revised to account for the latest developments, including the use of CCDs. Highly illustrated, this book provides an overview and historical background of the subject before reviewing the main themes within astronomical photometry. The central chapters focus on the practical design of the instruments and methodology used. The book concludes by discussing specialized topics in stellar astronomy, concentrating on the information that can be derived from the analysis of the light curves of variable stars and close binary systems. This new edition includes numerous bibliographic notes and a glossary of terms. It is ideal for graduate students, academic researchers and advanced amateurs interested in practical and observational astronomy. Edwin Budding is a research fellow at the Carter Observatory, New Zealand, and a visiting professor at the Çanakkale University, Turkey. Osman Demircan is Director of the Ulupınar Observatory of Çanakkale University, Turkey. Cambridge Observing Handbooks for Research Astronomers Today’s professional astronomers must be able to adapt to use telescopes and interpret data at all wavelengths. This series is designed to provide them with a collection of concise, self-contained handbooks, which covers the basic principles peculiar to observing in a particular spectral region, or to using a special technique or type of instrument. The books can be used as an introduction to the subject and as a handy reference for use at the telescope, or in the office. -

1 How Will Astronomy Archives Survive the Data Tsunami?
DATABASES HOW WILL ASTRONOMY ARCHIVES SURVIVE THE DATA TSUNAMI? Astronomers are collecting more data than ever. What practices can keep them ahead of the flood? G. Bruce Berriman, NASA Exoplanet Science Institute, Infrared Processing and Analysis Center Steven L. Groom, Infrared Processing and Analysis Center, California Institute of Technology Astronomy is already awash with data: currently 1 PB (petabyte) of public data is electronically accessible, and this volume is growing at 0.5 PB per year. The availability of this data has already transformed research in astronomy, and the STScI (Space Telescope Science Institute) now reports that more papers are published with archived data sets than with newly acquired data.17 This growth in data size and anticipated usage will accelerate in the coming few years as new projects such as the LSST (Large Synoptic Survey Telescope), ALMA (Atacama Large Millimeter Array), and SKA (Square Kilometer Array) move into operation. These new projects will use much larger arrays of telescopes and detectors or much higher data acquisition rates than are now used. Projections indicate that by 2020, more than 60 PB of archived data will be accessible to astronomers.9 THE TSUNAMI HAS ALREADY MADE LANDFALL The data tsunami is already affecting the performance of astronomy archives and data centers. One example is the NASA/IPAC (Infrared Processing and Analysis Center) IRSA (Infrared Science Archive), which archives and serves data sets from NASA’s infrared missions. It is going through a period of Growth in the -
NASA Shutting Down Space Telescope, Infrared Eyes to Cosmos 29 January 2020, by Marcia Dunn
NASA shutting down space telescope, infrared eyes to cosmos 29 January 2020, by Marcia Dunn put the aging spacecraft into permanent hibernation. For years, Spitzer peered through dusty clouds at untold stars and galaxies, uncovered a huge, nearly invisible ring around Saturn, and helped discover seven Earth-size planets around a nearby star. Spitzer's last observation was expected Wednesday. Altogether, Spitzer observed 800,000 celestial targets and churned out more than 36 million raw images as part of the $1.4 billion mission. An estimated 4,000 scientists around the world took part in the observations and published nearly 9,000 studies, according to NASA. "You have to be proud ... when you look back and say, 'Look at the team that's operating Spitzer, look at the team that's contributing to having all of this great science,' " said project manager Joseph This composite image made available by NASA shows a Hunt. neutron star, center, left behind by the explosion from the original star's death in the constellation Taurus, Designed to last just 2.5 years to five years, the observed on Earth as the supernova of A.D. 1054.

Binocular Universe: Hail the Queen November 2010
Binocular Universe: Hail the Queen November 2010 Phil Harrington hope you're dressed appropriately, because this month we have an audience with the Queen…Queen Cassiopeia, that is. Cassiopeia reigns over the autumn I sky as she rides high in the north, sitting on her royal throne. You have probably heard the story of Queen Cassiopeia, of how she and King Cepheus ruled ancient Ethiopia. Cassiopeia was well known for two things: her great beauty and her shameless arrogance. One day, she bragged of being more beautiful than the sea nymphs, who were well-known for their exquisite loveliness. Above: Autumn star map from Star Watch by Phil Harrington Above: Finder chart for this month's Binocular Universe. Chart adapted from Touring the Universe through Binoculars Atlas (TUBA), www.philharrington.net/tuba.htm The sea nymphs overheard this boasting and complained to their father, Poseidon, the king of the seas. Poseidon became so infuriated that he created Cetus the Sea Monster. Cetus was sent to Ethiopia to devour the citizens of the land. King Cepheus was told that his people could be saved only if he were to sacrifice his daughter Andromeda to the sea monster. As king, he had no alternative but to lead his daughter to the water's edge and chain her to a rock. There, she was left to the mercy of Cetus. Just then, our hero, Perseus, appeared on the scene. Perseus, the son of Zeus, had been ordered to kill a gorgon called Medusa. Medusa was a very ugly creature whose hair was made of snakes.
