    The Sky Is Not the Limit: Mutual Trust and Mutual Recognition aprés Aranyosi and Căldăraru

    Get PDF
    In the present article, judgments of the European Court of Justice, together with the case of Aranyosi and Căldăraru, are put under the academic microscope. The analysis is conducted through the lenses of domestic judges. It starts by drawing a broader picture of the challenges that the domestic judiciary faces when it comes to EU criminal law, in particular the mutual recognition instruments. It argues that judges are faced not only with the legal framework of sometimes questionable quality but also with potential conflicts of loyalty resulting from the multiplicity and occasional inconsistency of applicable legal regimes. In turn, the analysis moves to the exegesis of the Aranyosi and Căldăraru line of jurisprudence, in particular to the already mentioned security vs justice conundrum, which domestic judges sometimes face. The article ends with conclusions looking into the current state of affairs, and suggestions are made regarding the way forward

    An Observational Limit on the Dwarf Galaxy Population of the Local Group

    We present the results of an all-sky, deep optical survey for faint Local Group dwarf galaxies. Candidate objects were selected from the second Palomar survey (POSS-II) and ESO/SRC survey plates and follow-up observations performed to determine whether they were indeed overlooked members of the Local Group. Only two galaxies (Antlia and Cetus) were discovered this way out of 206 candidates. Based on internal and external comparisons, we estimate that our visual survey is more than 77% complete for objects larger than one arc minute in size and with a surface brightness greater than an extremely faint limit over the 72% of the sky not obstructed by the Milky Way. Our limit of sensitivity cannot be calculated exactly, but is certainly fainter than 25 magnitudes per square arc second in R, probably 25.5 and possibly approaching 26. We conclude that there are at most one or two Local Group dwarf galaxies fitting our observational criteria still undiscovered in the clear part of the sky, and a roughly a dozen hidden behind the Milky Way. Our work places the "missing satellite problem" on a firm quantitative observational basis. We present detailed data on all our candidates, including surface brightness measurements.Comment: 58 pages in AJ manuscript format; some figures at slightly reduced quality; accepted by the Astronomical Journa
