2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large…
Validating full-spectrum fitting with a synthetic integral-field spectroscopic observation of the Milky Way
Zixian Wang, Michael R. Hayden, Sanjib Sharma +5
Ongoing deep IFS observations of disk galaxies provide opportunities for comparison with the Milky Way (MW) to understand galaxy evolution. However, such comparisons are marred by…
Detecting a disk bending wave in a barred-spiral galaxy at redshift 4.4
Takafumi Tsukui, Emily Wisnioski, Joss Bland-Hawthorn +4
The recent discovery of barred spiral galaxies in the early universe () poses questions of how these structures form and how they influence galaxy evolution in the early unive…
Beyond BPT: A New Multi-Dimensional Diagnostic Diagram for Classifying Power Sources Tested Using the SAMI Galaxy Survey
Victor Johnston, Anne Medling, Brent Groves +11
Current methods of identifying the ionizing source of nebular emission in galaxies are well defined for the era of single fiber spectroscopy, but still struggle to differentiate th…
Asteroseismology with the Roman Galactic Bulge Time-Domain Survey
Daniel Huber, Marc Pinsonneault, Paul Beck +24
Asteroseismology has transformed stellar astrophysics. Red giant asteroseismology is a prime example, with oscillation periods and amplitudes that are readily detectable with time-…
GAMA/DEVILS: Cosmic star formation and AGN activity over 12.5 billion years
Jordan C. J. D'Silva, Simon P. Driver, Claudia D. P. Lagos +11
We use the Galaxy and Mass Assembly (GAMA) and the Deep Extragalactic Visible Legacy Survey (DEVILS) observational data sets to calculate the cosmic star formation rate (SFR) and a…
The MAGPI Survey: Impact of environment on the total internal mass distribution of galaxies in the last 5 Gyr
Caro Derkenne, Richard M. McDermid, Adriano Poci +20
We investigate the impact of environment on the internal mass distribution of galaxies using the Middle Ages Galaxy Properties with Integral field spectroscopy (MAGPI) survey. We u…
Galaxy And Mass Assembly (GAMA): The group HI mass as a function of halo mass
Ajay Dev, Simon P. Driver, Martin Meyer +11
We determine the atomic hydrogen (HI) to halo mass relation (HIHM) using Arecibo Legacy Fast ALFA survey HI data at the location of optically selected groups from the Galaxy and Ma…
The far side of the Galactic bar/bulge revealed through semi-regular variables
Daniel R. Hey, Daniel Huber, Benjamin J. Shappee +8
The Galactic bulge and bar are critical to our understanding of the Milky Way. However, due to the lack of reliable stellar distances, the structure and kinematics of the bulge/bar…
The GALAH survey: New diffuse interstellar bands found in residuals of 872,000 stellar spectra
Rok Vogrinčič, Janez Kos, Tomaž Zwitter +11
We use more than 872,000 mid-to-high resolution (R 20,000) spectra of stars from the GALAH survey to discern the spectra of diffuse interstellar bands (DIBs). We use four wi…
The SAMI-Fornax Dwarfs Survey III: Evolution of [/Fe] in dwarfs, from Galaxy Clusters to the Local Group
J. Romero-Gómez, Reynier F. Peletier, J. A. L. Aguerri +10
Using very deep, high spectral resolution data from the SAMI Integral Field Spectrograph we study the stellar population properties of a sample of dwarf galaxies in the Fornax Clus…
The rapid onset of stellar bars in the baryon-dominated centers of disk galaxies
J. Bland-Hawthorn, T. Tepper-Garcia, O. Agertz +1
Recent observations of high-redshift galactic disks () show a strong negative trend in the dark matter fraction with increasing baryonic surface density. For…
Evolution in the orbital structure of quiescent galaxies from MAGPI, LEGA-C and SAMI surveys: direct evidence for merger-driven growth over the last 7 Gy
Francesco D'Eugenio, Arjen van der Wel, Joanna M. Piotrowska +37
We present the first study of spatially integrated higher-order stellar kinematics over cosmic time. We use deep rest-frame optical spectroscopy of quiescent galaxies at redshifts…
The SAMI Galaxy Survey: Environmental analysis of the orbital structures of passive galaxies
Giulia Santucci, Sarah Brough, Jesse van de Sande +11
Most dynamical models of galaxies to date assume axisymmetry, which is not representative of a significant fraction of massive galaxies. We have built triaxial orbit-superposition…
Different higher-order kinematics between star-forming and quiescent galaxies based on the SAMI, MAGPI and LEGA-C surveys
Francesco D'Eugenio, Arjen van der Wel, Caro Derkenne +38
We present the first statistical study of spatially integrated non-Gaussian stellar kinematics spanning 7 Gyr in cosmic time. We use deep, rest-frame optical spectroscopy of massiv…
