Chemical abundances and properties of the ionized gas in NGC 1705
F. Annibali, M. Tosi, A. Pasquali +3
We obtained [O III] narrow-band imaging and multi-slit MXU spectroscopy of the blue compact dwarf (BCD) galaxy NGC 1705 with FORS2@VLT to derive chemical abundances of PNe and H II…
A disrupted bulgeless satellite galaxy as counterpart of the ultraluminous X-ray source ESO 243-49 HLX-1
M. Mapelli, F. Annibali, L. Zampieri +1
The point-like X-ray source HLX-1, close to the S0 galaxy ESO 243-49, is one the strongest intermediate-mass black hole candidates, but the nature of its counterpart is still puzzl…
A minor merger scenario for the ultraluminous X-ray source ESO 243-49 HLX-1 - II. Constraints from photometry
M. Mapelli, F. Annibali, L. Zampieri +1
The point-like X-ray source HLX-1, close to the S0 galaxy ESO 243-49, is the brightest known ultraluminous X-ray source and one the strongest intermediate-mass black hole candidate…
A minor merger scenario for the ultraluminous X-ray source ESO 243-49 HLX-1
M. Mapelli, L. Zampieri, L. Mayer
The point-like X-ray source HLX-1 is the brightest known ultraluminous X-ray source and likely the strongest intermediate-mass black hole candidate. HLX-1 is hosted in the S0 galax…
Nature and nurture of early-type dwarf galaxies in low density environments
R. Grützbauch, F. Annibali, R. Rampazzo +2
We study stellar population parameters of a sample of 13 dwarf galaxies located in poor groups of galaxies using high resolution spectra observed with VIMOS at the ESO-VLT. LICK-in…
Nearby early-type galaxies with ionized gas VI. The Spitzer-IRS view
P. Panuzzo, R. Rampazzo, A. Bressan +5
We present low resolution Spitzer-IRS spectra of 40 ETGs, selected from a sample of 65 ETGs showing emission lines in their optical spectra. We homogeneously extract the mid-infrar…
