GRB 051008: A long, spectrally hard dust-obscured GRB in a lyman-break galaxy at z ≈ 2.8*

We present observations of the dark gamma-ray burst GRB 051008 provided by Swift/BAT, Swift/XRT, Konus-WIND, INTEGRAL/SPI-ACS in the high-energy domain and the Shajn, Swift/UVOT, Tautenburg, NOT, Gemini and Keck I telescopes in the optical and near-infrared bands. The burst was detected only in gamma- and X-rays and neither a prompt optical nor a radio afterglow was detected down to deep limits. We identified the host galaxy of the burst, which is a typical Lyman-break galaxy (LBG) with R-magnitude of 24.06 ± 0.10 mag. A redshift of the galaxy of z = 2.77+0.15-0.20 is measured photometrically due to the presence of a clear, strong Lyman-break feature. The host galaxy is a small starburst galaxy with moderate intrinsic extinction (AV = 0.3) and has a star formation rate of ~60M( yr-1 typical for LBGs. It is one of the few cases where a GRB host has been found to be a classical LBG. Using the redshift we estimate the isotropic-equivalent radiated energy of the burst to be Eiso = (1.15 ± 0.20) × 1054 erg.We also provide evidence in favour of the hypothesis that the darkness ofGRB051008 is due to local absorption resulting from a dense circumburst medium © 2014 The Authors

Charitable Giving and Lay Morality: Understanding Sympathy, Moral Evaluations and Social Positions

This paper examines how charitable giving offers an example of lay morality, reflecting people’s capacity for fellow-feeling, moral sentiments, personal reflexivity, ethical dispositions, moral norms and moral discourses. Lay morality refers to how people should treat others and be treated by them, matters that are important for their subjective and objective well-being. It is a first person evaluative relation to the world (about things that matter to people). While the paper is sympathetic to the ‘moral boundaries’ approach, which seeks to address the neglect of moral evaluations in sociology, it reveals this approach to have some shortcomings. The paper argues that although morality is always mediated by cultural discourses and shaped by structural factors, it also has a universalising character because people have fellow-feelings, shared human conditions, and have reason to value

The Spectral Evolution of the First Galaxies. III. Simulated James Webb Space Telescope Spectra of Reionization-epoch Galaxies with Lyman-continuum Leakage

Using four different suites of cosmological simulations, we generate synthetic spectra for galaxies with different Lyman continuum escape fractions (fesc) at redshifts z=7-9, in the rest-frame wavelength range relevant for the James Webb Space Telescope (JWST) NIRSpec instrument. By investigating the effects of realistic star formation histories and metallicity distributions on the EW(Hb)-beta diagram (previously proposed as a tool for identifying galaxies with very high fesc), we find that neither of these effects are likely to jeopardize the identification of galaxies with extreme Lyman continuum leakage. Based on our models, we expect essentially all z=7-9 galaxies that exhibit rest-frame EW(Hb)0.5. Incorrect assumptions concerning the ionizing fluxes of stellar populations or the dust properties of z>6 galaxies can in principle bias the selection, but substantial model deficiencies of this type will at the same time reveal themselves as an offset between the observed and simulated distribution of z>6 galaxies in the EW(Hb)-beta diagram. Such offsets would thereby allow JWST/NIRSpec measurements of these observables to serve as input for further model refinement.Comment: 12 pages, 8 figures, v.2: ApJ, accepted.

Civic pride and redevelopment in the post-war British city

ABSTRACT:This article is concerned with civic pride in post-war urban Britain. While many of the development projects during 1945–79 proved to be design failures, suggesting the demise of civic pride, the ambitions of local authorities, planners and developers have largely been ignored or dismissed. Nevertheless, the development plans which emerged during this period reveal a desire to rebuild new, modern and vibrant cities. Moreover, the planning and financing of these new projects highlights the structure of local governance in post-war Britain, with a shift towards new partnerships consisting of the council, the technocrat and the developer. As such, civic pride continued to be evident in the post-war period, both as an aspiration for urban development and as a symbolic form of power.</jats:p

The Entrepreneurial City: The Role of Local Government and City-Centre Redevelopment in Post-War Industrial English Cities

This article will look at one of the key aspects in the role of local government in post-war Britain by considering how local authorities adopted broadly entrepreneurial strategies, working in partnership with the private sector, to attract investment and redevelop large sections of Britain�s major city centres from the late 1950s to the early 1970s. Focusing on some of the traditional industrial cities, it will examine the idea of the entrepreneurial city and how, while it has come to partially define the role of local government from the 1980s onwards, broadly similar approaches and attitudes to city-centre development were a marked feature of the role of local government policies from a much earlier period
