High-quality Spectrophotometry of the Planetary Nebula in the Fornax dSph
A. Y. Kniazev, E. K. Grebel, S. A. Pustilnik +1
We present results of NTT spectroscopy of the one known planetary nebula (PN) in the dwarf spheroidal galaxy Fornax, a gas-deficient Local Group galaxy that stopped its star format…
HS 2134+0400 - new very metal-poor galaxy, a representative of void population?
S. A. Pustilnik, D. Engels, A. Y. Kniazev +3
We present the SAO 6m telescope spectroscopy of a blue compact galaxy (BCG) HS 2134+0400 discovered in frame of the dedicated Hamburg/SAO survey for Low Metallicity BCGs (HSS-LM).…
Study of DDO 68: nearest candidate for a young galaxy?
S. A. Pustilnik, A. Y. Kniazev, A. G. Pramskij
We present the results of optical spectroscopy and imaging with the SAO 6m telescope for the dwarf galaxy DDO 68 (UGC 5340 = VV 542), falling into the region of very low density of…
The Hamburg/SAO survey for emission-line galaxies. VI. The sixth list of 126 galaxies
S. A. Pustilnik, D. Engels, V. A. Lipovetsky +12
We present the sixth list with results of the Hamburg/SAO Survey for Emission-Line Galaxies. The final list resulted from follow-up spectroscopy conducted with the 4.5m MMT telesco…
Spectrophotometry of Sextans A and B: Chemical Abundances of HII Regions and Planetary Nebulae
Alexei Y. Kniazev, Eva K. Grebel, Simon A. Pustilnik +2
We present the results of high quality long-slit spectroscopy of planetary nebulae (PNe) and HII regions in the two dwarf irregular galaxies Sextans A and B, which belong to a smal…
Spectroscopy of PNe in Sextans A, Sextans B, NGC 3109 and Fornax
Alexei Y. Kniazev, Eva K. Grebel, Alexander G. Pramskij +1
Planetary nebulae (PNe) and HII regions provide a probe of the chemical enrichment and star formation history of a galaxy from intermediate ages to the present day. We present the…
