We present observations and 3D gasdynamic simulations of the jet and knots of the K 4-47 planetary nebula (PN) with the purpose of comparing the observed and...
Accreting black holes and neutron stars release an unknown fraction of the infalling particles and energy in the form of collimated jets. The jets themselves...
Jets and Jet-Like Structures of Low-Ionization in Planetary Nebulae
In this contribution we discuss new results of a program aimed at studying the physical properties, origin and evolution of ``low-ionization, small-scale...
JHK imaging photometry is reported of an area of approximately 2'x3' centred on the far infrared source NGC 6334 I with limiting magnitudes J=18.3, H=17.8 and K...
Sub-arcsecond JHK images of the star formation region NGC 6334 IV covering 14.7arcmin2 have been obtained. These were supplemented by H2 and Brγ images of the...
Coordinates (J2000) and JHK photometry are given for the 493 sources detected with PANIC on Baade Telescope in an area of 111"x111" centred on G85.40+0.00 as...
