Detection of PAH and Far-Infrared Emission from the Cosmic Eye
Accepted for publication in ApJ A Preprint typeset using LTEX style emulateapj v. 08/22/09 DETECTION OF PAH AND FAR-INFRARED EMISSION FROM THE COSMIC EYE: PROBING THE DUST AND STAR FORMATION OF LYMAN BREAK GALAXIES B. Siana1, Ian Smail2, A. M. Swinbank2, J. Richard2, H. I. Teplitz3, K. E. K. Coppin2, R. S. Ellis1, D. P. Stark4, J.-P. Kneib5, A. C. Edge2 Accepted for publication in ApJ ABSTRACT ∗ We report the results of a Spitzer infrared study of the Cosmic Eye, a strongly lensed, LUV Lyman Break Galaxy (LBG) at z =3.074. We obtained Spitzer IRS spectroscopy as well as MIPS 24 and 70 µm photometry. The Eye is detected with high significance at both 24 and 70 µm and, when including +4.7 11 a flux limit at 3.5 mm, we estimate an infrared luminosity of LIR = 8.3−4.4 × 10 L⊙ assuming a magnification of 28±3. This LIR is eight times lower than that predicted from the rest-frame UV properties assuming a Calzetti reddening law. This has also been observed in other young LBGs, and indicates that the dust reddening law may be steeper in these galaxies. The mid-IR spectrum shows strong PAH emission at 6.2 and 7.7 µm, with equivalent widths near the maximum values observed in star-forming galaxies at any redshift. The LP AH -to-LIR ratio lies close to the relation measured in local starbursts. Therefore, LP AH or LMIR may be used to estimate LIR and thus, star formation rate, of LBGs, whose fluxes at longer wavelengths are typically below current confusion limits. -

Archons (Commanders) [NOTICE: They Are NOT Anlien Parasites], and Then, in a Mirror Image of the Great Emanations of the Pleroma, Hundreds of Lesser Angels
A R C H O N S HIDDEN RULERS THROUGH THE AGES A R C H O N S HIDDEN RULERS THROUGH THE AGES WATCH THIS IMPORTANT VIDEO UFOs, Aliens, and the Question of Contact MUST-SEE THE OCCULT REASON FOR PSYCHOPATHY Organic Portals: Aliens and Psychopaths KNOWLEDGE THROUGH GNOSIS Boris Mouravieff - GNOSIS IN THE BEGINNING ...1 The Gnostic core belief was a strong dualism: that the world of matter was deadening and inferior to a remote nonphysical home, to which an interior divine spark in most humans aspired to return after death. This led them to an absorption with the Jewish creation myths in Genesis, which they obsessively reinterpreted to formulate allegorical explanations of how humans ended up trapped in the world of matter. The basic Gnostic story, which varied in details from teacher to teacher, was this: In the beginning there was an unknowable, immaterial, and invisible God, sometimes called the Father of All and sometimes by other names. “He” was neither male nor female, and was composed of an implicitly finite amount of a living nonphysical substance. Surrounding this God was a great empty region called the Pleroma (the fullness). Beyond the Pleroma lay empty space. The God acted to fill the Pleroma through a series of emanations, a squeezing off of small portions of his/its nonphysical energetic divine material. In most accounts there are thirty emanations in fifteen complementary pairs, each getting slightly less of the divine material and therefore being slightly weaker. The emanations are called Aeons (eternities) and are mostly named personifications in Greek of abstract ideas. -

Just like biology, chemistry, geology, and physics, as- tronomers collect data, analyze that data, attempt to understand the object/subject they are looking at, and submit their results for publication. Along thewayas- tronomers use all of the mathematical techniques and physics necessary to understand the objects they examine. Thus, just like any other science, a largenumberofmath- ematical tools and concepts are needed to perform astronomical research. In today’s introductory lab, you will review and learn some of the most basic concepts neces- sary to enable you to successfully complete the various laboratory exercises you will encounter later this semester. When needed, the weekly laboratory exercise you are performing will refer back to the examples in this introduction—so keep the worked examples you will do today with you at all times during the semester to use as a refer- ence when you run into these exercises later this semester (in fact, on some occasions your TA might have you redo one of the sections of this lab for review purposes). -

12 Strong Gravitational Lenses
12 Strong Gravitational Lenses Phil Marshall, MaruˇsaBradaˇc,George Chartas, Gregory Dobler, Ard´ısEl´ıasd´ottir,´ Emilio Falco, Chris Fassnacht, James Jee, Charles Keeton, Masamune Oguri, Anthony Tyson LSST will contain more strong gravitational lensing events than any other survey preceding it, and will monitor them all at a cadence of a few days to a few weeks. Concurrent space-based optical or perhaps ground-based surveys may provide higher resolution imaging: the biggest advances in strong lensing science made with LSST will be in those areas that benefit most from the large volume and the high accuracy, multi-filter time series. In this chapter we propose an array of science projects that fit this bill. We first provide a brief introduction to the basic physics of gravitational lensing, focusing on the formation of multiple images: the strong lensing regime. Further description of lensing phenomena will be provided as they arise throughout the chapter. We then make some predictions for the properties of samples of lenses of various kinds we can expect to discover with LSST: their numbers and distributions in redshift, image separation, and so on. This is important, since the principal step forward provided by LSST will be one of lens sample size, and the extent to which new lensing science projects will be enabled depends very much on the samples generated. From § 12.3 onwards we introduce the proposed LSST science projects. This is by no means an exhaustive list, but should serve as a good starting point for investigators looking to exploit the strong lensing phenomenon with LSST. -
12.748 Lecture 2 Cosmic Abundances, Nucleosynthesis and Element Origins
12.748 Lecture 2 Cosmic Abundances, Nucleosynthesis and Element Origins Our intent is to shed further light on the reasons for the abundance of the elements. We made progress in this regard when we discussed nuclear stability and nuclear binding energy explaining the zigzag structure, along with the broad maxima around Iron and Lead. The overall decrease with mass, however, arises from the creation of the universe, and the fact that the universe started out with only the most primitive building blocks of matter, namely electrons, protons and neutrons. The initial explosion that created the universe created a rather bland mixture of just hydrogen, a little helium, and an even smaller amount of lithium. The other elements were built from successive generations of star formation and death. The Origin of the Universe It is generally accepted that the universe began with a bang, not a whimper, some 15 billion years ago. The two most convincing lines of evidence that this is the case are observation of • the Hubble expansion: objects are receding at a rate proportional to their distance • the cosmic microwave background (CMB): an almost perfectly isotropic black-body spectrum Isotopes 12.748 Lecture 2: Cosmic Abundances, Nucleosynthesis and Element Origins 1 In the initial fraction of a second, the temperature is so hot that even subatomic particles like neutrons, electrons and protons fall apart into their constituent pieces (quarks and gluons). These temperatures are well beyond anything achievable in the universe since. As the fireball expands, the temperature drops, and progressively higher-level particles are manufactured. By the end of the first second, the temperature has dropped to a mere billion degrees or so, and things are starting to get a little more normal: electrons, neutrons and protons can now exist. -
