Detection of He++ ion in the star-forming ring of the Cartwheel using MUSE data and ionizing mechanisms
Y. D. Mayya, A. Plat, V. M. A. Gómez-González +3
We here report the detection of the nebular HeII4686 line in 32 HII regions in the metal-poor collisional ring galaxy Cartwheel using the Multi-Unit Spectroscopic Explorer (MUSE) d…
Planetary nebulae with Wolf-Rayet-type central stars -- III. A detailed view of NGC 6905 and its central star
V. M. A. Gómez-González, G. Rubio, J. A. Toalá +6
We present a multi-wavelength characterisation of the planetary nebula (PN) NGC 6905 and its [Wolf-Rayet]-type ([WR]) central star (CSPN) HD 193949. Our Nordic Optical Telescope (N…
Planetary nebulae with Wolf-Rayet-type central stars -- II. Dissecting the compact planetary nebula M2-31 with GTC MEGARA
J. S. Rechy-García, J. A. Toalá, S. Cazzoli +4
We present a comprehensive analysis of the compact planetary nebula M2-31 investigating its spectral properties, spatio-kinematical structure and chemical composition using GTC MEG…
Tomography of the unique on-going jet in the planetary nebula NGC 2392
M. A. Guerrero, S. Cazzoli, J. S. Rechy-Garcia +5
Jets (fast collimated outflows) are claimed to be the main shaping agent of the most asymmetric planetary nebula (PNe) as they impinge on the circumstellar material at late stages…
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…
Discovery of a Fast Expanding Shell in the Inside-out Born-Again Planetary Nebula HuBi 1 Through High-Dispersion Integral Field Spectroscopy
J. S. Rechy-García, M. A. Guerrero, E. Santamaría +8
HuBi 1 has been proposed to be member of the rare class of born-again planetary nebulae (PNe), i.e., its central star experienced a very late thermal pulse and ejected highly-proce…
Unveiling the stellar origin of the Wolf-Rayet nebula NGC6888 through infrared observations
G. Rubio, J. A. Toalá, P. Jiménez-Hernández +5
We present a comprehensive infrared (IR) study of the iconic Wolf-Rayet (WR) wind-blown bubble NGC6888 around WR136. We use Wide-field Infrared Survey Explorer (WISE), Spitzer IRAC…
MEGARA-IFU detection of extended HeII4686 nebular emission in the central region of NGC1569 and its ionization budget
Y. D. Mayya, E. Carrasco, V. M. A. Gomez-Gonzalez +21
We here report the detection of extended HeII4686 nebular emission in the central region of NGC1569 using the integral field spectrograph MEGARA at the 10.4-m Gran Telescopio Canar…
Planetary nebulae with Wolf-Rayet-type central stars -- I. The case of the high-excitation NGC 2371
V. M. A. Gómez-González, J. A. Toalá, M. A. Guerrero +4
We present the analysis of the planetary nebula (PN) NGC 2371 around the [Wolf-Rayet] ([WR]) star WD 0722295. Our Isaac Newton Telescope (INT) Intermediate Dispersion Spectrogra…
The Bubble Nebula NGC 7635 -- testing the wind-blown bubble theory
J. A. Toalá, M. A. Guerrero, H. Todt +5
We present a multiwavelength study of the iconic Bubble Nebula (NGC 7635) and its ionising star BD602522. We obtained XMM-Newton EPIC X-ray observations to search for…
Wolf-Rayet stars in M81 using GTC/OSIRIS: 7 new detections, analysis and classification of the full sample
V. M. A. Gómez-González, Y. D. Mayya, D. Rosa-González +3
We report the detection of 7 new Wolf-Rayet (WR) star locations in M81 using the Multi-Object Spectrograph of the OSIRIS instrument at Gran Telescopio Canarias. These detections ar…
Wolf-Rayet stars in M81: Detection and Characterization using GTC/OSIRIS spectra and HST/ACS images
V. M. A. Gomez-Gonzalez, Y. D. Mayya, D. Rosa-Gonzalez
We here report the properties of Wolf-Rayet (W-R) stars in 14 locations in the nearby spiral galaxy M81. These locations were found serendipitously while analysing the slit spectra…
