When Galaxies Refuel: Evolution of the Perturbed Spiral Galaxy NGC1385
Xiaoyu Kang, Eva Sextl, Rolf-Peter Kudritzki +5
The spiral galaxy NGC 1385 is characterized by a vigorous and protracted history of star formation, particularly in its central regions, leading to a current star formation rate th…
Blue supergiants and the zero point of the Tully-Fisher relation: a path to a new independent test of the Hubble constant
Rolf-Peter Kudritzki, Fabio Bresolin, Miguel A. Urbaneka +1
Blue supergiant distances of nearby galaxies obtained with the flux-weighted gravity-luminosity relationship are used for a measurement of the zero points of Tully-Fisher relations…
The Hidden Story of Chemical Evolution in Local Star-Forming Nuclear Rings
Eva Sextl, Rolf-Peter Kudritzki
A VLT/MUSE population synthesis study of metallicities in the nuclear star-forming rings of four disk galaxies (NGC 613, NGC 1097, NGC 3351, NGC 7552) is presented. Disentangling t…
Blue supergiants in the Pinwheel Galaxy M101: comparison with H II region chemical abundances, spectroscopic distance and an independent determination of the Hubble constant
Fabio Bresolin, Rolf-Peter Kudritzki, Miguel A. Urbaneja +2
We present a quantitative spectroscopic study of 13 blue supergiant stars in the Pinwheel Galaxy M101, based on data obtained with the Low Resolution Imaging Spectrometer available…
The TYPHOON Stellar Population Synthesis Survey. II. Pushing Full Spectral Fitting to the Limit in the Nearby Grand Design Barred Spiral M83
Eva Sextl, Rolf-Peter Kudritzki, Fabio Bresolin +7
We apply population synthesis techniques to analyze TYPHOON long slit spectra of the starburst barred spiral galaxy M83. The analysis covers a central square of 5 arcmin side lengt…
Quantifying azimuthal variations within the interstellar medium of z ~ 0 spiral galaxies with the TYPHOON survey
Qian-Hui Chen, Kathryn Grasha, Andrew J. Battisti +13
Most star formation in the local Universe occurs in spiral galaxies, but their origin remains an unanswered question. Various theories have been proposed to explain the development…
Galaxy spectroscopy without spectra: Galaxy properties from photometric images with conditional diffusion models
Lars Doorenbos, Eva Sextl, Kevin Heng +6
Modern spectroscopic surveys can only target a small fraction of the vast amount of photometrically cataloged sources in wide-field surveys. Here, we report the development of a ge…
The TYPHOON stellar population synthesis survey: I. The young stellar population of the Great Barred Spiral NGC 1365
Eva Sextl, Rolf-Peter Kudritzki, Andreas Burkert +6
We analyze TYPHOON long slit absorption line spectra of the starburst barred spiral galaxy NGC 1365 obtained with the Progressive Integral Step Method covering an area of 15 square…
Mass Metallicity Relationship of SDSS Star Forming Galaxies: Population Synthesis Analysis and Effects of Star Burst Length, Extinction Law, Initial Mass Function and Star Formation Rate
Eva Sextl, Rolf-Peter Kudritzki, H. Jabran Zahid +1
We investigate the mass-metallicity relationship of star forming galaxies by analysing the absorption line spectra of 200,000 galaxies in the Sloan Digital Sky Survey. The ga…
Modified Gravity and the Flux-weighted Gravity-Luminosity Relationship of Blue Supergiant Stars
Eva Sextl, Rolf-Peter Kudritzki, Jochen Weller +2
We calculate models of stellar evolution for very massive stars and include the effects of modified gravity to investigate the influence on the physical properties of blue supergia…
Towards early-type eclipsing binaries as extragalactic milestones: II. NLTE spectral analysis and stellar parameters of the detached O-type system OGLE-LMC-ECL-06782 in the LMC
Mónica Taormina, Rolf-Peter Kudritzki, Joachim Puls +5
We combine the NLTE spectral analysis of the detached O-type eclipsing binary OGLE-LMC-ECL-06782 with the analysis of the radial velocity curve and light curve to measure an indepe…
