Star Formation Rates in Nearby Markarian Galaxies

2014

The star formation rates for the 230 nearest Markarian galaxies with radial velocities VLG <3500 km/s have been determined from their far ultraviolet fluxes obtained with the GALEX satellite. We briefly discuss the observed relationship between the star formation rate and other integral parameters of these galaxies: stellar mass, hydrogen mass, morphological type, and activity index. On the average, the Markarian galaxies have reserves of gas that are a factor of two smaller than those of galaxies in the field of the same stellar mass and type. Despite their elevated activity, the specific rate of star formation in the Markarian galaxies, SF R/M * , does not exceed a limit of ∼dex(-9.4) [yr −1 ].

“…Absolute magnitudes M B were calculated using Galactic Standard of Rest (V G ) velocities (RC3), while optical and H I heliocentric velocities (V R ) were considered for redshift corrections in the IUE spectra. The main sources (and references therein) were: RC3 (identifications, PGC number, T , V R , A B , B, V G for M B calculations); Sandage & Tammann (1981) for V G in some groups of galaxies; Mazzarella & Balzano (1986) for data on Markarian galaxies; Véron & Véron (1991) and Hewitt & Burbidge (1993) for data on AGNs. Additional relevant references are given in Sect.…”

Abstract. -We analyse the UV properties of early-type galaxies from their UV spectra in the IUE library, including both normal and active nuclei. We co-added the spectra, and hence the objects into groups of similar spectral properties in the UV, also taking into account their properties in the visible/near-infrared ranges. Although, owing to the presence of a residual fixed pattern noise, IUE data cannot be improved by co-addition as expected for spectra containing only random noise, this procedure still provided spectra of higher signal/noise ratio than in previous studies, often based on individual spectra and therefrom derived colour indices. Thanks to the co-adding procedure, information on spectral features can now be assessed. The red stellar population groups exhibit a far-UV flux at different levels. The higher ones denote the presence of the UV turnup, which possibly exhibits absorption features, at least as detected through the IUE aperture. As to the blue stellar population groups and/or AGNs, we have carried out simple syntheses with UV star cluster templates and galaxy spectra in order to infer the properties such as burst ages and contamination by an active nucleus. It has been possible to derive information on the extinction law affecting some internally reddened galaxies; there are cases where the presence of the λ2200Å absorption feature suggests a reddening law similar to the Galactic one, and others without the λ2200Å feature, suggesting that it is rather an SMC type law which applies, then.

“…Even though entries on the Markarian list were all identified in a common manner based on their apparent blueness, they constitute a diverse set of astrophysical objects, ranging from nearby blue stars superimposed on normal galaxies to distant quasars (Mazzarella & Balzano 1986). In almost all cases emission lines have been confirmed in follow-up studies (e.g.…”

Abstract. The recently published ZORROASTER catalogue is being expanded into what will eventually be a complete list of known 'nearby' (z < 0.1) AGN, with optical spectral images, detailed spectral descriptors and waveband-specific flux ratios included where available. The first version of ZORROASTER contained 2843 entries characterised by confirmed or previously suspected broad H-beta emission, and 1000 spectral images. The 2nd version of ZORROASTER was released during the conference, and (in addition to serendipitous updates) includes all z < 0.1 objects from the list of Markarian. Activity classes and spectral descriptions of Markarian objects have been reviewed, and comparisons of flux ratios derived from the 100 ZORROASTER wavelength-specific pass bands are presented for those Markarian AGN for which Sloan Digital Sky Survey spectra exist. The value of the improved parameterizations and classifications of the Markarian objects on AGN studies, and the implications on some past investigations based on the Markarian lists, are briefly discussed.
