“…Such orbitally related changes should be also observed in the Balmer UV continuum. In fact, the Galaxy Evolution Explorer (GALEX) (Martin et al 2005;Morrissey et al 2007) observations of LMC S63 resulted in F(NUV)=647.59+/-13.48 mJy on MJD 55803 (φ = 0.700), and F(NUV)=553.52+/-7.92 mJy on MJD 55903 (φ = 0.796), and they seem to reflect mostly the expected changes in the Balmer continuum.…”

We present an analysis of multi-epoch low-resolution spectrophotometry, complemented by the light curves provided by massive photometric surveys spanning over 100 years, of the symbiotic binary LMC S63. We showed that it is an eclipsing binary with the orbital period of 1050 d . We also found evidence of outbursts in history of the white dwarf. If it was a Z-And type outburst, as is most likely, it would be a second such outburst recorded in the Magellanic Cloud symbiotic system. We confirmed that the red giant is enhanced in carbon, and estimated C/O ≃ 1.2 by fitting a model atmosphere to the SALT spectrum. We also found bi-periodic pulsations of the red giant, and demonstrated that it is similar to other carbon variables with confirmed bi-periodicity.

“…GCAT does not include the GALEX GR7 data release and so, when necessary, we also draw values from the BCS catalogue. We use magnitudes obtained from the Medium Imaging Survey (MIS; see Martin et al 2005) images for the ninety-six per cent of the Figure 2. NUV-r colour versus stellar mass diagram for galaxies in our sample.…”

We revisit the main H i-to-stellar mass ratio (gas fraction) scaling relations, taking advantage of the HI spectral stacking technique to understand the dependence of gas content on the structural and star formation properties of nearby galaxies. This work uses a volume-limited, multi-wavelength sample of ∼25,000 galaxies, selected according to stellar mass (10 9 M M 10 11.5 M ) and redshift (0.02 z 0.05) from the Sloan Digital Sky Survey, and with H i data from the Arecibo Legacy Fast ALFA survey. We bin according to multiple parameters of galaxies spanning the full gas-poor to -rich regime in order to disentangle the dominance of different components and processes in influencing gas content. For the first time, we show that the scaling relations of gas fraction with stellar mass and stellar surface density are primarily driven by a combination of the underlying galaxy bimodality in specific star formation rate and the integrated Kennicutt-Schmidt law. Finally, we produce tentative evidence that the timescales of H i depletion are dependent upon galaxy mass and structure, at fixed specific star formation rate.

We address the relation between star formation and active galactic nucleus (AGN) activity in a sample of 231 nearby (0.0002 < z < 0.0358) early-type galaxies by carrying out a multi-wavelength study using archival observations in the UV, IR, and radio. Our results indicate that early-type galaxies in the current epoch are rarely powerful AGNs, with P 10 WHz 22 1 < -for a majority of the galaxies. Only massive galaxies are capable of hosting powerful radio sources while less massive galaxies are hosts to lower radio power sources. Evidence of ongoing star formation is seen in approximately 7% of the sample. The star formation rate (SFR) of these galaxies is less than 0.1 M e yr −1 . They also tend to be radio faint (P 10 WHzThere is a nearly equal fraction of star-forming galaxies in radio faint (P 10 WHz 22 1 < -) and radio bright galaxies (P 10 WHz 22 1  -) suggesting that both star formation and radio mode feedback are constrained to be very low in our sample. We notice that our galaxy sample and the Brightest Cluster Galaxies follow similar trends in radio power versus SFR. This may be produced if both radio power and SFR are related to stellar mass.
