New results of a program to study BAL + IR + FeII QSOs, using Gemini/GMOS-IFU spectroscopy and HST data, are presented for IRAS 17002+5153 and IRAS 07598+6508. In particular, the Gemini GMOS-IFU data show that: (i) IRAS 17002+5153: the 3D spectra in the region of the shells (at radius of 1.3") show multiple emission line components (with Δ V~280-

We present age and metallicity determinations for 49 star clusters in the SMC from Washington CT1 photometry and integrated spectra. Two of the observed clusters resulted to be relatively old object (age ~ 6.5 Gyr). In addition, we confirm that the further a cluster is from the center of the galaxy, the older and more metal-poor it is, with some

We obtained the spectrum of probability of the bremsstrahlung emission accompanying the α-decay of 226Ra (Eα = 4.8 MeV) by measuring the α-γ coincidences and using the model presented in our previous study on the α-decay of 214Po (Eα = 7.7 MeV). We compare the experimental data with the quantum mechanical calculation and find a good agreement

Ks-band images of 20 barred galaxies show an increase in the peak amplitude of the normalized m=2 Fourier component with the R25-normalized radius at this peak. This implies that longer bars have higher m=2 amplitudes. The long bars also correlate with an increased density in the central parts of the disks, as measured by the luminosity inside 0

The paper describes the different methods, used in the MAGIC experiment, to unfold experimental energy distributions of cosmic ray particles (γ-rays). Questions and problems related to the unfolding are discussed. Various procedures are proposed which can help to make the unfolding robust and reliable. The different methods and procedures are
