In this paper we review the modeling of the Local Bubble (LB) with special emphasis on the progress we have made since the last major conference “The Local Bubble and Beyond (I)” held in Garching in 1997. Since then new insight was gained into the possible origin of the LB, with a moving group crossing its volume during the last 10 15 Myr being most likely responsible for creating a local cavit...

Most of the linguistic resources available to day are about the world’s major languages. This paper discusses two projects which have world-wide coverage as their aim. Glottolog/Langdoc is an attempt to attain near-complete bibliographical coverage for the world’s lesser-known languages (i.e. 95% of the world’s linguistic diversity), which then provides solid empirical ground for extensional de...

We have detected two high ionization phases of gas in the z ∼ 2.77 partial Lyman limit system (LLS) towards QSO 1157+3143 . We detect the first phase by CIV and SiIV absorption, and the second phase – which is either warmer or undergoing larger random bulk motions than the first – via OVI absorption. Both phases of gas are present in similar column density ratios in each of the 5 velocity compo...

We have conducted a systematic survey for intervening OVI absorbers in available echelle spectra of 16 QSOs at zQSO = 0.17 − 0.57. These spectra were obtained using HST/STIS with the E140M grating. Our search uncovered a total of 27 foreground O VI absorbers with rest-frame absorption equivalent width Wr(1031) & 25 mÅ. Ten of these QSOs exhibit strong OVI absorbers in their vicinity. Our OVI su...

This note investigates whether gains from lottery wins are strictly randomized across lottery winners. Using a unique longitudinal dataset of lottery winners in Britain, we offer new evidence that certain socio-economic characteristics strongly predict future winnings in the national lottery. This is the case even after controlling for individual fixed effects in the estimation. Researchers wor...

In this paper, the late-time optical photometry of supernova (SN) 1993J in M81 from Feburary 1995 to Janurary 2003 is presented. The observations were performed in a set of intermediate-band filters that have the advantage of tracing the strength variations of some spectral features. SN 1993J was found to fade very slowly at late times, declining only by 0.05±0.02 mag 100 d in most of the filte...
