THE ACTIVE NUCLEUS OF IC 4970: A NEARBY EXAMPLE OF MERGER-INDUCED COLD-GAS ACCRETION
No full textWe present results from ChandraX-ray and Spitzer mid-infrared observations of the interacting galaxy pair NGC 6872/IC 4970 in the Pavo galaxy group and show that the smaller companion galaxy IC 4970 hosts a highly obscured active galactic nucleus (AGN). The 0.5Y10 keVX-ray luminosity of the nucleus is variable, increasing by a factor 2.9 to a luminosity of 1:7; 1042 erg s1 (bright state) on 100 ks timescales. The X-ray spectrum of the bright state is heavily absorbed (NH 3; 1023 cm2 for power-law models with 1:5Y2:0) and shows a clear 6.4 keV Fe K line with equivalent width of 144Y195 eV. Limits on the diffuse emission in IC 4970 from Chandra X-ray data suggest that the available power from Bondi accretion of IC 4970’s hot interstellar gas may be an order of magnitude too small to power the AGN. Spitzer images show that 8mnonstellar emission is concentrated in the central 1 kpc of IC 4970, consistent with high obscuration in this region. The mid-infrared colors of the nucleus are consistent with those expected for a highly obscured AGN. Taken together these data suggest that the nucleus of IC 4970 is a Seyfert 2, triggered and fueled by cold material supplied to the central supermassive black hole as a result of the off-axis colli-sion of IC 4970 with the cold-gas-rich spiral galaxy NGC 6872
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
