webSME: An online tool to infer stellar parameters and abundances

Johannes Puschnig, Andreas J. Korn, Jonathan Remmert, Ivy Balkwill-Western et autres

Stellar spectroscopy is a robust technique for determining fundamental stellar parameters such as effective temperature, surface gravity and metallicity. Spectroscopy Made Easy (SME) has long served as a framework for spectral synthesis and parameter inference. In this paper, we introduce webSME, a …

The properties and kinematics of HCN emission across the closest starburst galaxy NGC 253 observed with ALMA

Ivana Bešlić, Ashley T. Barnes, Frank Bigiel, María J. Jiménez-Donaire et autres

Context. Investigating molecular gas tracers, such as hydrogen cyanide (HCN), to probe higher densities than CO emission across nearby galaxies remains challenging. This is due to the large observing times required to detect HCN at a high sensitivity and spatial resolution. Although …

End-to-end simulation framework for astronomical spectrographs: SOXS, CUBES, and ANDES

Andrea Scaudo, Matteo Genoni, Gianluca Li Causi, Lorenzo Cabona et autres

We present our numerical simulation approach for the End-to-End (E2E) model applied to various astronomical spectrographs, such as SOXS (ESO-NTT), CUBES (ESO-VLT), and ANDES (ESO-ELT), covering multiple wavelength regions. The E2E model aim at simulating the expected astronomical observations starting from the …

The properties and kinematics of HCN emission across the closest starburst galaxy NGC 253 observed with ALMA

Ivana Bešlić, Ashley T. Barnes, Frank Bigiel, María J. Jiménez-Donaire et autres

Studying molecular gas in nearby galaxies using hydrogen cyanide (HCN) as a tracer for higher densities than CO emission still poses a significant challenge. Even though several galaxies have HCN maps on a few kpc scales, higher-resolution maps are still required. Our …

The reliability of satellite-based lighttrends for dark sky areas in Austria

Stefan Wallner, Johannes Puschnig, S. Stidl

Globally, light pollution is a phenomenon rising in its appearance and threatening human health and natural habitats for flora and fauna. Consequently, there is a great interest in interdisciplinary communities to keep an eye on its occurrence and development. One possibility to …

The EDGE-CALIFA Survey: Spatially Resolved 13CO(1–0) Observations and Variations in 12CO(1–0)/13CO(1–0) in Nearby Galaxies on Kiloparsec Scales

Yixian Cao, Tony Wong, Alberto D. Bolatto, Adam K. Leroy et autres

Abstract We present 13CO(J = 1 → 0) observations for the EDGE-CALIFA survey, which is a mapping survey of 126 nearby galaxies at a typical spatial resolution of 1.5 kpc. Using detected 12CO emission as a prior, we detect 13CO in 41 …

Unveiling the gravitationally unstable disc of a massive star-forming galaxy using NOEMA and MUSE

Johannes Puschnig, Matthew Hayes, Oscar Agertz, Éric Emsellem et autres

ABSTRACT Using new high-resolution data of CO (2–1), H$\alpha$ and H$\beta$ obtained with the Northern Extended Millimeter Array (NOEMA) and the Multi-Unit Spectroscopic Explorer (MUSE) at the Very Large Telescope, we have performed a Toomre Q disc stability analysis and studied star …

We present 13CO(1-0) observations for the EDGE-CALIFA survey, which is a mapping survey of 126 nearby galaxies at a typical spatial resolution of 1.5 kpc. Using detected 12CO(1-0) emission as a prior, we detect 13CO(1-0) in 41 galaxies via integrated line flux …

Wide-field CO isotopologue emission and the CO-to-H 2 factor across the nearby spiral galaxy M101

Jakob S. den Brok, Frank Bigiel, Jérémy Chastenet, Karin M. Sandstrom et autres

Carbon monoxide (CO) emission constitutes the most widely used tracer of the bulk molecular gas in the interstellar medium (ISM) in extragalactic studies. The CO-to-H 2 conversion factor, α 12 CO(1−0) , links the observed CO emission to the total molecular gas …
