“…To address the goals of our current study of examining the evolution of the nuclear and star formation activ-ities in compact groups, a multi-wavelength coverage of the sample is essential. We cross-correlated Catalogue-A with the ultraviolet (UV) all sky survey of Galaxy Evolution Explorer (GALEX; Morrissey et al 2005), as well as the nearinfrared (NIR) and mid-infrared (MIR) surveys of 2MASS (Skrutskie et al 2006) and WISE (Wright et al 2010) respectively. Since the only selection criterion we applied was the availability of UV-to-MIR observations for a group as opposed to an individual galaxy, our sub-sample is also complete as the original Catalogue-A.…”

Abstract:Research addressing collective memory in the Czech context is predominantly based on the constructivist approach laid out by Maurice Halbwachs. This approach can be characterized by an assumption of omnipresent existence of stable structures of meaning with which action is explained. In the existing literature, we can also find alternative approaches based on findings of the cognitive sciences. These approaches can be characterized by searching for neurophysiological invariants which determine the diffusion of cultural representations. With respect to this state of the research field, the aim of this text is twofold. First, to demonstrate that the assumptions highlighting supra-individual semantic structures introduced by the Halbwachsian tradition lead to premature closure of explanation, without taking into account the question of diffusion of semantic structures. Second, to show that the focus on cognitive phenomena (taking into account the question of diffusion of semantic structures) does not have to lead to acceptance of reductionist premises. As a result, this study attempts to suggest an approach which would be able to study collective memory without reliance on supra-individual entities on the one hand and on reductionist assumptions on the other. It seems that the approach of Situational Analysis fits those criteria well and therefore it is introduced in the concluding parts of the text. ÚvodVýzkumu kolektivní paměti se v současné době věnuje mnoho badatelů v České republice i v zahraničí. Jde také o pole bádání, které není jednoznačně vymezeno ve vztahu k existujícím oborům. Relevantní v tomto ohledu nejsou jen sociologie a historie (či historická sociologie), ale -jak uvidíme -například i kognitivní vědy. Z tohoto pohledu se pak může zdát překvapivé, že obvykle podávaná vysvětlení fenoménů vztahujících se ke kolektivní paměti mají v určitém smyslu homogenní povahu. Tato společná tendence se projevuje selektivním zaměřením bádání na určitý typ empirického materiálu a nezohledňováním působení typů jiných. Cílem tohoto textu je poukázat na zmíněnou společnou tendenci ve vysvětlování jevů kolektivní paměti, zvážit limitace, jež jsou s touto tendencí spojeny, a navrhnout alternativní přístup, který by se těmto limitacím mohl vyhnout.* Tento text vznikl v rámci řešení výzkumného projektu podpořeného Grantovou agenturou České republiky (GAČR P404 14-01948S).

“…Using the latest W ISE (Wright et al 2010) all sky release, we obtained the photometry or the upper limits for the galaxies in our sample. W ISE was a 40cm telescope, which performed all sky survey, covering the 3.4, 4.6, 12.0, and 22.0µm bands (named w1-to-w4), with 5-σ sensitivity limits 19.70-to-14.40 mags, respectively.…”

We present the first -of a series -study of the evolution of galaxies in compact groups over the past 3 Gyr. This paper focuses on the evolution of the nuclear activity and how it has been affected by the dense environment of the groups. Our analysis is based on the largest multiwavelength compact group sample to-date, containing complete ultraviolet-to-infrared (UV-to-IR) photometry for 1,770 isolated groups (7,417 galaxies). We classified the nuclear activity of the galaxies based on optical emission line and mid-infrared diagnostic methods, as well as using spectral energy distribution fitting. We observe a 15% increase on the number of the AGN-hosting late-type galaxies found in dynamically old groups, over the past 3 Gyr, accompanied by the corresponding decrease of their circumnuclear star formation. Comparing our compact group results with those of local isolated field and interacting pair galaxies, we find no differences in the AGN at the same redshift range. Based on both optical and mid-IR colour classifications, we report the absence of Seyfert 1 nuclei and we attribute this to the low accretion rates, caused by the depletion of gas. We propose that the observed increase of LINER and Seyfert 2 nuclei (at low-z's), in the early-type galaxies of the dynamically young groups, is due to the morphological transformation of lenticular into elliptical galaxies. Finally, we show that at any given stellar mass, galaxies found in dynamically old groups are more likely to host an AGN. Our findings suggest that the depletion of gas, due to past star formation and tidal stripping, is the major mechanism driving the evolution of the nuclear activity in compact groups of galaxies.
