Possible optical detection of a fast, nearby radio pulsar PSR B1133+16
S. V. Zharikov, Yu. A. Shibanov, R. E. Mennickent +1
Aims: We performed deep optical observations of the field of an old, fast-moving radio pulsar PSR B1133+16 in an attempt to detect its optical counterpart and a bow shock nebula. M…
Are the compact star clusters in M82 evolving towards globular clusters?
Y. D. Mayya, D. Rosa-Gonzalez, L. Rodriguez +3
Recent HST/ACS images of M82 covering the entire galaxy have been used to detect star clusters. The galaxy is known to contain a young population (age < 10 Myr) in its starburst nu…
Population synthesis at short wavelengths and spectrophotometric diagnostic tools for galaxy evolution
A. Buzzoni, E. Bertone, M. Chavez +1
Taking advantage of recent important advances in the calculation of high-resolution spectral grids of stellar atmospheres at short wavelengths, and their implementation for populat…
Re-born fireballs in Gamma-Ray Bursts
G. Ghisellini, A. Celotti, G. Ghirlanda +2
We consider the interaction between a relativistic fireball and material assumed to be still located just outside the progenitor star. Only a small fraction of the expected mass is…
Deep optical observations of the interaction of the SS 433 microquasar jet with the W 50 radio continuum shell
P. Boumis, J. Meaburn, J. Alikakos +6
Four mosaics of deep, continuum-subtracted, CCD images have been obtained over the extensive galactic radio continuum shell, W 50, which surrounds the remarkable stellar system SS…
Keck spectroscopy and Spitzer Space Telescope analysis of the outer disk of the Triangulum Spiral Galaxy M33
David L. Block, Francoise Combes, Ivanio Puerari +11
In an earlier study of the spiral galaxy M33, we photometrically identified arcs or outer spiral arms of intermediate age (0.6 Gyr - 2 Gyr) carbon stars precisely at the commenceme…
