SDSS-V Local Volume Mapper (LVM): Helix Nebula public data, Data Analysis Pipeline data products
S. F. Sánchez, J. E. Méndez-Delgado, A. Mejía-Narváez +21
We present a spatially resolved spectroscopic analysis of the Helix Nebula (NGC 7293) using data from the SDSS-V Local Volume Mapper (LVM), by applying the recently developed LVM D…
A targeted radio survey of infrared-selected bow shock candidates
M. Moutzouri, J. Mackey, N. Castro +8
Bow shocks around massive stars have primarily been detected in IR emission, but radio detections are becoming more frequent with the commissioning of sensitive and large field-of-…
Catching the Butterfly and the Homunculus of Carinae with ALMA
Luis A. Zapata, Laurent Loinard, Manuel Fernández-López +7
The nature and origin of the molecular gas component located in the circumstellar vicinity of Carinae are still far from being completely understood. Here, we present Atacama L…
The Nearby Evolved Stars Survey II: Constructing a volume-limited sample and first results from the James Clerk Maxwell Telescope
P. Scicluna, F. Kemper, I. McDonald +89
The Nearby Evolved Stars Survey (NESS) is a volume-complete sample of 850 Galactic evolved stars within 3\,kpc at (sub-)mm wavelengths, observed in the CO (21) and…
Dust in RCW 58: clues to common envelope channel formation?
P. Jiménez-Hernández, S. J. Arthur, J. A. Toalá +1
We present a characterization of the dust in the Wolf-Rayet (WR) nebula RCW 58 around the WN8h star WR 40 using archival infrared (IR) observations from WISE and Herschel and radio…
Carbon dust in the evolved born-again planetary nebulae A30 and A78
J. A. Toalá, P. Jiménez-Hernández, J. B. Rodríguez-González +6
We present an infrared (IR) characterization of the born-again planetary nebulae (PNe) A30 and A78 using IR images and spectra. We demonstrate that the carbon-rich dust in A30 and…
Wolf-Rayet stars in the Antennae unveiled by MUSE
V. M. A. Gómez-González, Y. D. Mayya, J. A. Toalá +3
We present the analysis of archival Very Large Telescope (VLT) Multi Unit Spectroscopic Explorer (MUSE) observations of the interacting galaxies NGC 4038/39 (a.k.a. the Antennae) a…
Dissecting the hot bubbles in LMC-N57 with XMM-Newton
I. Ramírez-Ballinas, J. Reyes-Iturbide, J. A. Toalá +1
We present a study of the diffuse X-ray emission from the star forming region LMC-N 57 in the Large Magellanic Cloud (LMC). We use archival XMM-Newton observations to unveil in det…
On the X-ray temperature of hot gas in diffuse nebulae
J. A. Toalá, S. J. Arthur
X-ray emitting diffuse nebulae around hot stars are observed to have soft-band temperatures in the narrow range [1-3] K, independent of the stellar wind parameters an…
Aspect Ratio Dependence of the Free-Fall Time for Non-Spherical Symmetries
Andy Pon, Jesús A. Toalá, Doug Johnstone +3
We investigate the collapse of non-spherical substructures, such as sheets and filaments, which are ubiquitous in molecular clouds. Such non-spherical substructures collapse homolo…
Rebirth of X-ray Emission from the Born-Again Planetary Nebula A 30
M. A. Guerrero, N. Ruiz, W. -R. Hamann +8
The planetary nebula (PN) A30 is believed to have undergone a very late thermal pulse resulting in the ejection of knots of hydrogen-poor material. Using HST images we have detecte…
