Collisionally excited filaments in HST H and H images of HH~1/2
A. C. Raga, B. Reipurth, A. Castellanos-Ramírez +2
We present new H and H images of the HH~1/2 system, and we find that the H/H ratio has high values in ridges along the leading edges of the HH~1 bow shock and of the br…
Interaction between the IGM and a dwarf galaxy
V. Lora, A. C. Raga, E. K. Grebel
Dwarf Galaxies are the most common objects in the Universe and are believed to contain large amounts of dark matter. There are mainly three morphologic types of dwarf galaxies: dwa…
A two-mode planetary nebula luminosity function
A. Rodríguez-González, L. Hernández-Martínez, A. Esquivel +4
We propose a new Planetary Nebula Luminosity Function (PNLF) that includes two populations in the distribution. Our PNLF is a direct extension of the canonical function proposed by…
An asymmetric jet launching model for the protoplanetary nebula CRL 618
P. F. Velazquez, A. Riera, A. C. Raga +1
We propose an asymmetrical jet ejection mechanism in order to model the mirror symmetry observed in the lobe distribution of some protoplanetary nebulae (pPNe), such as the pPN CRL…
Age, size, and position of H ii regions in the Galaxy. Expansion of ionized gas in turbulent molecular clouds
P. Tremblin, L. D. Anderson, P. Didelon +8
This work aims at improving the current understanding of the interaction between H ii regions and turbulent molecular clouds. We propose a new method to determine the age of a larg…
A Stellar Wind Origin for the G2 Cloud: Three-Dimensional Numerical Simulations
Fabio De Colle, A. C. Raga, Flavio F. Contreras-Torres +1
We present 3D, adaptive mesh refinement simulations of G2, a cloud of gas moving in a highly eccentric orbit towards the galactic center. We assume that G2 originates from a stella…
