We present VR magnification ratios of QSO 0957+561 that are inferred from the GLITP light curves of Q0957+561A and new frames taken with the 2.56 m Nordic...

We study the evolutionary path of the Fornax Cluster galaxy NGC 1436, which is known to be currently transitioning from a spiral into a lenticular morphology...

We present spectroscopic observations of supernova 1994D in NGC 4526, an S0_3_ galaxy in the Virgo cluster 15Mpc distant. The datasets consist of the...

We report the case of the early-type disk galaxy NGC 4672 as a new example of a galaxy characterized by the orthogonal geometrical decoupling between bulge and...

Targets were selected from existing V- and I-band photometry obtained as part of the ongoing ARAUCARIA Cepheid search project whose results have been reported...

NGC 5506 is a peculiar Seyfert (Sy) galaxy: it has a Sy2-like optical spectrum, but broad permitted infrared lines and a high X-ray luminosity as compared with...

The existence of massive galaxies lacking a classical bulge has often been proposed as a challenge to ΛCDM. However, recent simulations propose that a fraction...

Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (PA =5°, 50°, 95...

Aims: NGC 6240 is a well-studied nearby galaxy system in the process of merging. Based on optical, X-ray, and radio observations, it is thought to harbor two...
