NLS1s and BLAGNs PAH
The differences between Narrow Line Seyfert 1 galaxies (NLS1s) and Broad Line AGNs (BLAGNs) are not completely understood; it is thought that they may have different... -
uvby{beta} photometry of NGC 663
We present CCD uvby{beta} photometry for stars in the central area of the young open cluster NGC 663. We find that the reddening is highly variable, with values ranging from... -
UBV and H-beta in Sco-Cen association
As part of a thorough study of the luminosity function of Sco-Cen, UBV, and H_{beta} photometry has been acquired for a large number of mid B- to late A-type stars which are... -
3C 390.3 BVRI and H photometry
Results of a ground-based optical monitoring campaign on 3C 390.3 in 1994-1995 are presented. The broadband fluxes (B, V, R, and I), the spectrophotometric optical continuum... -
Spectroscopy and photometry follow up for NGC 4151
Changing-look active galactic nucleus NGC4151, which has attracted a lot of attention, is undergoing the second dramatic outburst stage in its evolutionary history. To... -
Reverberation mapping of the Seyfert Zw I 1
We report results of the first reverberation mapping campaign of I Zwicky 1 during 2014-2016, which showed unambiguous reverberations of the broad H{beta} line emission in the... -
CANDELS z~2 galaxy properties
We use CANDELS imaging, 3D-HST spectroscopy, and Chandra X-ray data to investigate if active galactic nuclei (AGNs) are preferentially fueled by violent disk instabilities... -
Stromgren photometry in M67
Precision CCD uvbyCaH{beta} photometry is presented of the old cluster, M67, covering one square degree with typical internal precision at the 0.005-0.020mag level to V~17. The... -
ELG luminosity functions in the nearby Universe
Nebular emission lines are powerful diagnostics for the physical processes at play in galaxy formation and evolution. Moreover, emission-line galaxies (ELGs) are one of the main... -
PHANGS-MUSE sample HII regions catalog
We use an unprecedented sample of about 23000 HII regions detected at an average physical resolution of 67pc in the PHANGS-MUSE sample to study the extragalactic HII region... -
Photometry & spectroscopy of EE Cep: 2014-15
EE Cep is one of few eclipsing binary systems with a dark, dusty disk around an invisible object similar to epsilon Aur. The system is characterized by grey and asymmetric... -
HII galaxies narrow-band Hbeta images
Our aims is to create a catalog of images of HII galaxies and their individual star-formation regions in order to study the distribution of the gas emission and their underlying... -
Computed Hbeta indices from ATLAS9 model
Grids of H{beta} indices based on updated (new-ODF) ATLAS9 model atmospheres were computed for solar and scaled solar metallicities [+0.5], [+0.2], [0.0], [-0.5], [-1.0],... -
uvby{beta} photometry of h and chi Per
We present CCD uvby{beta} photometry for stars in the nuclei of the young double cluster {h} and {chi} Persei. We find that the reddening is highly variable through the {h} Per... -
HII regions in NGC 5457 and NGC 4395
Line intensities, visual extinction, abundances and ionization hardness parameter for HII regions in two spiral galaxies are presented. The following galaxies have been... -
