The extended HeII4686 emission in the extremely metal-poor galaxy SBS0335-052E seen with MUSE
C. Kehrig, J. M. Vilchez, M. A. Guerrero +4
SBS0335-052E, one of the most metal-poor (Z ~ 3-4% Z) HeII-emitter starbursts known in the nearby universe, is studied using optical VLT/MUSE spectroscopic and Chandra X-…
On the relationship between the H2 emission and the physical structure of planetary nebulae
R. A. Marquez-Lugo, G. Ramos-Larios, M. A. Guerrero +1
Mid-IR observations of planetary nebulae (PNe) have revealed diffuse emission associated to their main nebular shells and outer envelopes or haloes. The interpretation of this emis…
NGC 6778: a disrupted planetary nebula around a binary central star
M. A. Guerrero, L. F. Miranda
The planetary nebula (PN) NGC 6778 harbors a binary central star with a short orbital period and displays two systems of fast collimated outflows. In order to assess the influence…
The collimated outflows of the planetary nebula Hu1-2: proper motion and radial velocity measurements
L. F. Miranda, M. Blanco, M. A. Guerrero +1
Hu\,1-2 is a planetary nebula that contains an isolated knot located northwestern of the main nebula, which could be related to a collimated outflow. We present a subsarcsecond H$α…
