Spectropolarimetric observations of the CIZA J2242.8+5301 northern radio relic: no evidence of high-frequency steepening
Observations of radio relics at very high frequency (>10 GHz) can help to understand how particles age and are (re-)accelerated in galaxy cluster outskirts and...
Spectropolarimetry of 3C 265, a misaligned radio galaxy
We present spectropolarimetry of the powerful radio galaxy 3C 265 at z=0.811. The rest-frame UV continuum, which has an elongated structure misaligned by about...
Spectroscopic Atlas of the Central 24^''x20^'' of the Seyfert 2 Galaxy NGC 1068
Two-dimensional spectroscopy of the central 24^''x20^'' of the Seyfert 2 galaxy NGC 1068 has been obtained using a fiber-optic system (2D-FIS). The homogeneity...
Spectroscopic characterization of the stellar content of ultra-diffuse galaxies
Understanding the peculiar properties of ultra-diffuse galaxies (UDGs) via spectroscopic analysis is a challenging task requiring very deep observations and...
Spectroscopic Confirmation of an Ultra Massive and Compact Galaxy At Z = 3.35: a Detailed Look At an Early Progenitor of Local Giant Ellipticals
We present the first spectroscopic confirmation of an ultramassive galaxy at redshift z\gt 3 using data from Keck-NIRSPEC, VLT-X-shooter, and GTC-Osiris. We...
Spectroscopic observations of AB supergiants in M 33.
We have observed 10 luminous blue stars in M 33 at intermediate dispersion and have determined spectral types and luminosity classes from the blue and red...
Spectroscopic observations of AB-supergiants in M 31 and M 33
We have observed a number of the most luminous A and B supergiants in the galaxies M 31 and M 33 at intermediate dispersion obtaining both blue and red...
Spectroscopic Properties of New IR Galaxies Detected in the European Large Area ISO Survey
We present preliminary results of multi-object spectroscopy of new mid-, and far-infrared selected galaxies detected in the European Large Area ISO Survey...
