The first "water fountain" collimated outflow in a planetary nebula
J. F. Gomez, O. Suarez, Ph. Bendjoya +8
"Water fountains" (WFs) are evolved objects showing high-velocity, collimated jets traced by water maser emission. Most of them are in the post-Asymptotic Giant Branch and they may…
NGC 6309, a Planetary Nebula that Shifted from Round to Multipolar
Gabriel Rubio, Roberto Vazquez, Gerardo Ramos-Larios +4
We present new narrow-band Ha, [N II], and [O III] high-resolution images of the quadrupolar planetary nebula (PN) NGC 6309 that show in great detail its bipolar lobes and reveal n…
How much dark matter is there inside early-type galaxies?
A. Nigoche-Netro, A. Ruelas-Mayorga, P. Lagos +5
We study the luminous mass as a function of the dynamical mass inside the effective radius (r_e) of early-type galaxies (ETGs) to search for differences between these masses. We as…
