MOLPOP-CEP: an exact, fast code for multi-level systems
We present MOLPOP-CEP, a universal line transfer code that allows the exact calculation of multi-level line emission from a slab with variable physical...
NGC 288 is a diffuse Galactic globular cluster; it is remarkable in that its low density results in internal accelerations being below the critical MOND a0...
Monitoring luminous yellow massive stars in M 33: new yellow hypergiant candidates
Context. The evolution of massive stars surviving the red supergiant (RSG) stage remains unexplored due to the rarity of such objects. The yellow hypergiants...
Monitoring of 3C 66A during an extended outburst. I. The light curves.
We present results from a two year intensive monitoring of BL Lac object 3C 66A (PKS 0219+428). This object was observed in outburst during these two years. It...
Monitoring of active galacitc nuclei. 4: The Seyfert 1 galaxy NGC 4593
Results of a five-month campaign of optical monitoring the Seyfert 1 galaxy NGC 4593 are presented. High resolution H-alpha and H-Beta spectra and direct images...
Monitoring of active galactic nuclei. I - The quasars 1302 - 102 and 1217 + 023
We present the results of a five-month spectroscopic monitoring campaign of two radio loud quasars, PKS 1217 + 023 and PKS 1302 - 102. There is a pronounced...
Monitoring of active galactic nuclei. V. The Seyfert 1 galaxy Markarian 279
We report on the Lovers of Active Galaxies' (LAG) monitoring of the Seyfert 1 galaxy Markarian 279 from January to June 1990. The source, which was in a very...
Monitoring of active galactic nuclei. VI. The quasar MKN 876.
We present the results of a 6 month monitoring campaign of Mkn 876, a low luminosity quasar with M_abs_=~-24. High resolution spectroscopy and direct imaging in...
