We present results of photometric observations of the high-amplitude EC 14026-type star, Balloon 090100001. The data were obtained in broad-band B filter and...

Balloon 090100001 is the brightest (B=11.8) pulsator sdB of the EC14026 class. Moreover, it shows a frequency mode (at 356 s, 2.81 mHz) with one of the hightest...

We present wide-field, spatially and highly resolved spectroscopic observations of Balmer filaments in the northeastern rim of Tycho's supernova remnant in...

Using the BaLROG (Bars in Low Redshift Optical Galaxies) sample of 16 morphologically distinct barred spirals, we constrain the influence of bars on nearby...

Stellar bars drive the galaxy secular evolution. While rotating around the galaxy centre with a given angular frequency, the bar pattern speed, they sweep...

Bars are ellipsoidal-like structures that appears in the inner regions of a large fraction of discs of galaxies. Bars universal features present at all galactic...

More than 10% of the barred galaxies with a direct measurement of bar pattern speed host a bar rotating extremely fast. These bars are generally defined as...

Using the gravitational torque indicator Qb, we derive the distribution of bar strengths for a sample of early-type disk galaxies. The sample is part of the...
