Planetary Nebula Central Stars as Tracers of Planetary Nebula-Star Cluster Associations in the Galaxy
Vasiliki Fragkou, Luis Lomelí-Núñez, Dante Minniti +2
Planetary nebulae (PNe) that are physically associated with star clusters are rare but crucial for stellar evolution studies because they allow their initial and final stellar prop…
Probing the origin of the kilonova candidate GRB 230307A: analysis of host galaxy and offset
Clecio R. Bom, Davi C. Rodrigues, Arianna Cortesi +12
We investigate the host galaxy of the long gamma-ray burst GRB 230307A, which is associated with a kilonova candidate likely produced by a binary neutron-star (BNS) merger. The tra…
The physical association of planetary nebula NGC 2818 with open cluster NGC 2818A
Vasiliki Fragkou, Roberto Vázquez, Quentin A. Parker +2
Planetary nebulae (PNe) that are physical members of open star clusters (OCs) are valuable for stellar evolution studies. They are extremely rare, with only three such instances co…
Spectroscopic and photometric confirmation of 3 globular and 14 intermediate-age clusters in the Irr II galaxy NGC3077
Pedro A. Ovando Ramirez, Y. D. Mayya, Lino H. Rodriguez-Merino +4
We present the results from spectroscopic and photometric analysis of 17 globular cluster (GC) candidates in the Irr II galaxy NGC 3077. The GC candidates were selected on the Hubb…
The relation between globular cluster systems and supermassive black holes in spiral galaxies III. The link to the correlation
Rosa A. González-Lópezlira, Luis Lomelí-Núñez, Yasna Ordenes-Briceño +6
We continue to explore the relationship between globular cluster total number, , and central black hole mass, , in spiral galaxies. We present here results f…
Star cluster survival in dark matter halos: An old cluster in Eridanus II?
Jairo A. Alzate, Verónica Lora, Gustavo Bruzual +2
The star formation history and the internal dynamics of Milky Way satellite galaxies are often complicated. In the last years, a substantial fraction of the known faint dwarf satel…
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…
Detection of the self-regulation of star formation in galaxy discs
Javier Zaragoza-Cardiel, Jacopo Fritz, Itziar Aretxaga +6
Stellar feedback has a notable influence on the formation and evolution of galaxies. However, direct observational evidence is scarce. We have performed stellar population analysis…
Spectroscopy of NGC 4258 globular cluster candidates: membership confirmation and kinematics
Rosa A. Gonzaléz-Lópezlira, Y. D. Mayya, Laurent Loinard +9
We present multi-object spectroscopic observations of 23 globular cluster candidates (GCCs) in the prototypical megamaser galaxy NGC 4258, carried out with the OSIRIS instrument at…
The relation between globular cluster systems and supermassive black holes in spiral galaxies. The case study of NGC 4258
Rosa A. González-Lópezlira, Luis Lomelí-Núñez, Karla Álamo-Martínez +7
We aim to explore the relationship between globular cluster total number, , and central black hole mass, , in spiral galaxies, and compare it with that recen…
