The haloes and environments of nearby galaxies (HERON) -- III. A 45 kpc spiral structure in the GLSB galaxy UGC 4599

Aleksandr V. Mosenkov, R. Michael Rich, Michael Fusco +10

We use a 0.7-m telescope in the framework of the Halos and Environments of Nearby Galaxies (HERON) survey to probe low surface brightness structures in nearby galaxies. One of our…

The globular cluster system of the nearest Seyfert II galaxy Circinus

C. Obasi, M. Gómez, D. Minniti +7

Context. The globular cluster (GC) system of Circinus galaxy has not been probed previously partly because of the location of the galaxy at - 3.8 Galactic latitude which su…

Discovery of new globular clusters in the Sagittarius dwarf galaxy

D. Minniti, V. Ripepi, J. G. Fernández-Trincado +14

Context. Globular clusters (GCs) are witnesses of the past accretion events onto the Milky Way (MW). In particular, the GCs of the Sagittarius (Sgr) dwarf galaxy are important prob…

The full spectral radiative properties of Proxima Centauri

Ignasi Ribas, Michael D. Gregg, Tabetha S. Boyajian +1

The discovery of Proxima b, a terrestrial temperate planet, presents the opportunity of studying a potentially habitable world in optimal conditions. A key aspect to model its habi…

Reverberation Mapping of the Kepler-Field AGN KA1858+4850

Liuyi Pei, Aaron J. Barth, Greg S. Aldering +40

KA1858+4850 is a narrow-line Seyfert 1 galaxy at redshift 0.078 and is among the brightest active galaxies monitored by the Kepler mission. We have carried out a reverberation mapp…
