MUSE crowded field 3D spectroscopy in NGC 300 : IV. Planetary nebula luminosity function

Azlizan A. Soemitro, Martin M. Roth, Peter M. Weilbacher +5

We perform a deep survey of planetary nebulae (PNe) in the spiral galaxy NGC 300 to construct its planetary nebula luminosity function (PNLF). We aim to derive the distance using t…

MUSE crowded field 3D spectroscopy in NGC 300 III. Characterizing extremely faint HII regions and diffuse ionized gas

Genoveva Micheva, Martin M. Roth, Peter M. Weilbacher +7

There are known differences between the physical properties of HII and diffuse ionized gas (DIG), but most of the studied regions in the literature are relatively bright. We compil…

A new reference catalogue for the very metal-poor Universe: +150 OB stars in Sextans A

Marta Lorenzo, Miriam Garcia, Francisco Najarro +3

Local Group (LG) very metal-poor massive stars are the best proxy for the First Stars of the Universe and fundamental to modelling the evolution of early galaxies. These stars may…

MUSE crowded field 3D spectroscopy in NGC 300 II. Quantitative spectroscopy of BA-type supergiants

Gemma González-Torà, Miguel A. Urbaneja, Norbert Przybilla +4

A quantitative spectral analysis of BA-type supergiants and bright giants in an inner spiral arm region of the nearby spiral galaxy NGC 300 is presented, based on observations with…

Resolving stellar populations with integral field spectroscopy

Martin M. Roth, Peter M. Weilbacher, Norberto Castro

High-performance instruments at large ground-based telescopes have made integral field spectroscopy (IFS) a powerful tool for the study of extended objects such as galaxies, nebula…

Resolved Kinematics of Runaway and Field OB Stars in the Small Magellanic Cloud

M. S. Oey, J. Dorigo Jones, N. Castro +6

We use GAIA DR2 proper motions of the RIOTS4 field OB stars in the Small Magellanic Cloud (SMC) to study the kinematics of runaway stars. The data reveal that the SMC Wing has a sy…
