Non-Axisymmetric Structure in the Satellite Dwarf Galaxy NGC2976: Implications for its Dark/Bright Mass Distribution and Evolution
O. Valenzuela, H. Hernández-Toledo, M. Cano-Díaz +4
We present the result of an extensive search for non-axisymmetric structures in the dwarf satellite galaxy of M81: NGC 2976, using multiwavelength archival observations. The galaxy…
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…
The Building of Galactic Disks: Insights from the Triangulum Spiral Galaxy Messier 33
D. L. Block, I. Puerari, G. G. Fazio +10
The Triangulum Spiral Galaxy Messier 33 offers unique insights into the building of a galactic disk. We identify spectacular arcs of intermediate age (0.6 Gyr - 2 Gyr) stars in the…
An almost head-on collision as the origin of two off-centre rings in the Andromeda galaxy
D. L. Block, F. Bournaud, F. Combes +6
The unusual morphology of the Andromeda Spiral (Messier 31, the closest spiral galaxy to the Milky Way) has long been an enigma. Although regarded for decades as showing little evi…
Coherent bremsstrahlung, coherent pair production, birefringence and polarimetry in the 20-170 GeV energy range using aligned crystals
NA59 Collaboration, A. Apyan, R. O. Avakian +27
The processes of coherent bremsstrahlung (CB) and coherent pair production (CPP) based on aligned crystal targets have been studied in the energy range 20-170 GeV. The experimental…
Results on the Coherent Interaction of High Energy Electrons and Photons in Oriented Single Crystals
NA59 Collaboration, A. Apyan, R. O. Avakian +27
The CERN-NA-59 experiment examined a wide range of electromagnetic processes for multi-GeV electrons and photons interacting with oriented single crystals. The various types of cry…
