Characterization of the MUSE NFM PSF as a function of atmospheric conditions: TipTop calibration
Enrico Congiu, Fuyan Bian, Carlo F. Manara +8
The Multi Unit Spectroscopic Explorer (MUSE) achieves exceptional spatial resolution in narrow-field mode (NFM) thanks to the GALACSI adaptive optics (AO) system. However, limitati…
SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss
Qian Zhai, Jujia Zhang, Xiaofeng Wang +51
We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…
Exploring the synergies of with MUSE spectroscopy in PHANGS H II regions
Eric Habjan, Kathryn Kreckel, Christopher Faesi +16
Spatially resolved maps of gas-phase metallicity provide key constraints on the chemical enrichment and mixing processes that drive galaxy evolution, but measurements based only on…
Late-time evolution of the interacting stripped-envelope supernova 2017dio
C. Humina, C. P. Gutiérrez, H. Kuncarayakti +14
The discovery of stripped-envelope supernovae (SNe) interacting with dense circumstellar medium (CSM) challenges our current understanding of massive star evolution. We present lat…
The transitional Type Ibn/IIn SN 2022pda, with pre-explosion outbursts and a double-peaked light curve
Y. -Z. Cai, A. Pastorello, R. Chiba +65
We report the results of a photometric and spectroscopic follow-up campaign of the unusual interacting supernova (SN) 2022pda. Precursor variability lasting days is obse…
AT 2025abao: The fourth luminous red nova in M 31
A. Reguitti, A. Pastorello, G. Valerin +15
We present photometric and spectroscopic observations of the luminous red nova (LRN) AT 2025abao, the fourth discovered in M 31. The LRN, associated to the asymptotic giant branch…
