Tracing Galaxy Evolution in the Nearby Universe: The Role of Dark Matter
A. Nigoche-Netro, P. Lagos, R. J. Diaz +6
Using a sample of 126000 late-type galaxies from the SDSS, we analyzed stellar mass as a function of the dynamical mass. Stellar masses are estimated using eight stellar population…
Identification of planetary and proto-planetary nebulae candidates through akari infrared photometry
R. A. Marquez-Lugo, S. N. Kemp, G. Ramos-Larios +3
We utilized photometric data from the space telescope AKARI to identify potential planetary nebulae (PNe) and proto-planetary nebulae (PPNe) candidates. Using the colour-colour dia…
Virial masses of late type galaxies from the SDSS DR16
A. Nigoche-Netro, E. de la Fuente, R. J. Diaz +6
Motivated by the challenges of calculating the dynamical masses of late-type galaxies (LTGs) and the enormous amount of data from the Sloan Digital Sky Survey (SDSS), we calculate…
The tidal filament of NGC 4660
S. N. Kemp, C. Martinez-Robles, R. A. Marquez-Lugo +6
NGC 4660, in the Virgo cluster, is a well-studied elliptical galaxy which has a strong disk component (D/T about 0.2-0.3). The central regions including the disk component have ste…
The excitation mechanism of H2 in bipolar planetary nebulae
R. A. Marquez-Lugo, Martin A. Guerrero, Gerardo Ramos-Larios +1
We present near-IR K-band intermediate-dispersion spatially-resolved spectroscopic observations of a limited sample of bipolar planetary nebulae (PNe). The spectra have been used t…
The born-again planetary nebula A78: an X-ray twin of A30
J. A. Toalá, M. A. Guerrero, H. Todt +8
We present the XMM-Newton discovery of X-ray emission from the planetary nebula (PN) A78, the second born-again PN detected in X-rays apart from A30. These two PNe share similar sp…
Expansion of hydrogen-poor knots in the born-again planetary nebulae A30 and A78
Xuan Fang, Martin A. Guerrero, Ramon A. Marquez-Lugo +8
We analyze the expansion of hydrogen-poor knots and filaments in the born-again planetary nebulae A30 and A78 based on Hubble Space Telescope (HST) images obtained almost 20 yr apa…
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…
Discovery of Multiple Shells Around the Planetary Nebula IC 418
Gerardo Ramos-Larios, Roberto Vazquez, Martin A. Guerrero +3
We have analysed optical, near-, and mid-IR images of the bright planetary nebula (PN) IC 418. These images probe unambiguously for the first time a number of low surface brightnes…
Mid and Far Infrared Photometry of Galactic Planetary Nebulae with the AKARI All Sky Survey
J. P. Phillips, R. A. Marquez-Lugo
We provide mid- and far-infrared photometry of 857 Galactic planetary nebulae (PNe) using data derived from the AKARI All-Sky Survey. These include fluxes at 9 and 18 μm obtained w…
MIPSGAL 24 μm Observations of Galactic Planetary Nebulae
J. P. Phillips, R. A. Marquez-Lugo
We have obtained 24 μm imaging, profiles and fluxes for 224 planetary nebulae (PNe) lying within the limits of the Spitzer MIPSGAL survey. It is noted that most of the PNe having e…
The Interaction of Supernova Remnant G357.7+0.3 with the Interstellar Medium
J. P. Phillips, R. A. Marquez-Lugo
The supernova remnant (SNR) G357.7+0.3 appears to have caused considerable shredding of the local interstellar medium (ISM), leading to the formation of multiple cloud fragments ha…
Imaging of Four Galactic Supernovae Remnants in the Mid-Infrared, and their Interaction with the Interstellar Medium
R. A. Marquez-Lugo, J. P. Phillips
We provide mid-infrared (MIR) imaging, photometry and profiles for the Galactic supernova remnants (SNRs) G001.0-00.1, G355.9-02.5, G355.6-00.0, and W28 based upon data deriving fo…
