Cosmic-ray electron propagation in the peculiar barred spiral galaxy NGC 2442
Shengtao Wang, Xiaohui Sun, Volker Heesen +13
Face-on spiral galaxies offer a favorable geometry for studying magnetic-field structures and cosmic-ray (CR) propagation because projection effects and structural overlap are redu…
An improved view of cosmic-ray transport and the galactic outflow in NGC 253
Shengtao Wang, George Heald, Stefan W. Duchesne +11
The nearly edge-on starburst galaxy NGC 253 exhibits extended multiwavelength halo emission, making it an ideal laboratory for studying disk-halo transport. We present improved ASK…
OutThere Survey: Addressing and with a population of average galaxies at z2
Ravi Jaiswar, Anshu Gupta, Elisabete da Cunha +24
Constraining the major contributors to the ionisation of the early universe is an ongoing endeavour of high-redshift galaxy research. We measure the ionising photon production effi…
The MAGPI survey: Stellar population radial trends and mass assembly in star-forming galaxies at z~0.3
Federica Mauro, Bodo Ziegler, Iris Breda +19
The evolution of galaxies from cosmic noon to the present day provides a key window to probe the balance between early, rapid bulge formation and prolonged disk growth. The epoch a…
EMU/GAMA: Refining Dust Extinction Corrections for Hα Luminosity Functions Using Radio-Based Calibration
J. Willingham, A. Hopkins, T. Zafar +17
We present a novel approach to correcting H luminosity functions for dust extinction by calibrating against radio-based star formation rates (SFRs), using data from the Evolutio…
The MAGPI Survey: co-evolution of baryons and dark matter in star-forming disk-like galaxies at
Gauri Sharma, Andrew J. Battisti, Emily Wisnioski +20
We present a comprehensive analysis of the dark matter (DM) content and its structural dependence in star-forming disk-like galaxies at intermediate redshifts ($0.1 \lesssim z \les…
A Census of Double-Peaked Lyman-alpha Emitters in MAGPI: Classification, Global Characteristics, and Spatially Resolved Properties
Tamal Mukherjee, Tayyaba Zafar, Themiya Nanayakkara +17
Double-peaked Ly profiles provide critical insights into gas kinematics and the distribution of neutral hydrogen (HI) from the interstellar to the intergalactic medium (ISM to I…
Discovery of a Little Red Dot candidate at in COSMOS-Web based on MIRI-NIRCam selection
Takumi S. Tanaka, Hollis B. Akins, Yuichi Harikane +64
JWST has revealed a new high-redshift population called little red dots (LRDs). Since LRDs may be in the early phase of black hole growth, identifying them in the early universe is…
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…
Galaxy And Mass Assembly: A new approach to quantifying dust in galaxies
B. Farley, U. T. Ahmed, A. M. Hopkins +8
We introduce a new approach to quantifying dust in galaxies by combining information from the Balmer decrement (BD) and the dust mass (). While there is no explicit correlatio…
The MAGPI Survey: Insights into the Lyman-alpha line widths and the size of ionized bubbles at the edge of cosmic reionization
T. Mukherjee, T. Zafar, T. Nanayakkara +18
We present spectroscopic properties of 22 Lyman-alpha emitters(LAEs) at z=5.5-6.6 with Lyman-alpha(Lya) luminosity log([])=42.4-43.5, obtained using VLT/MUSE as…
The spatially resolved relation between dust, gas, and metal abundance with the TYPHOON survey
Hye-Jin Park, Andrew J. Battisti, Emily Wisnioski +12
We present the spatially resolved relationship between the dust-to-gas mass ratio (DGR) and gas-phase metallicity (Zgas or 12+log(O/H)) (i.e., DGR-Zgas relation) of 11 nearby galax…
The ALMA-CRISTAL Survey: Spatially-resolved Star Formation Activity and Dust Content in 4 < z < 6 Star-forming Galaxies

Using a combination of HST, JWST, and ALMA data, we perform spatially resolved spectral energy distributions (SED) fitting of fourteen 4<z<6 UV-selected main-sequence galaxies targ…
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…
