Moderate resolution near-infrared mapping of the M31 bulge component is presented, and the structure, and radial color index and surface brightness variations...

NGC 2841 has been mapped in the J and K near-infrared bands out to some 10 kpc from its center. Maps and radial profiles in micron(J), micron(K) and J-K are...

Four radial profiles of M 31 in the near infrared taken with the 1.5 m infrared telescope of the Observatorio del Teide, Tenerife are presented. Three of these...

Near-infrared maps in the J, H, and K bands, have been obtained for the nearby flocculent spiral NGC 2403, with a linear resolution of 900 pc. Radially and...

The authors present the results of a near-infrared survey of 13 areas containing 16 GGD objects. A total of 12 infrared sources have been detected in five of...

In the present results from a program of near-IR scanning of planetary nebulae, the observed flux is in most cases dominated by free-free emission. In three of...

Topics discussed in this issue include active galaxies and cosmology, interstellar and intergalactic medium, and astronomical instrumentation. Papers are...

Narrow-band H-alpha images and long-slit spectroscopy of the Seyfert galaxy NGC 985 are presented. Large-scale extended ionized zones are seen to cover a...

Although the QSO PKS 2128 - 123 appears as highly variable in the I band, with Delta-I of up to 1.69 mag, it is a moderate amplitude variable object in the...
