SN 2024afyu interpreted as a Pair Instability Supernova
P. J. Pessi, S. Barmentloo, Ł. Wyrzykowski +63
Pair-instability supernovae (PISNe) are the predicted explosions of very massive stars triggered by electron-positron pair production. Numerous transients have been proposed as PIS…
Peak 'Nebular' Emission and Early Flux Excesses in Ca-strong Supernovae
C. -G. Touchard-Paxton, K. Maguire, C. Frohmaier +27
Calcium-strong supernovae (Ca-strong SNe) are a class of thermonuclear transient characterised by rapid photometric evolution (rise times of <= 16 d) and nebular-phase spectra domi…
GOTO identification and broadband modelling of the counterpart to the SVOM GRB 250818B
S. Belkin, G. P. Lamb, K. Ackley +61
Rapid localisation and follow-up of gamma-ray bursts (GRBs) increasingly rely on low-latency triggers from new missions coupled to wide-field robotic optical facilities. We present…
The ambiguous AT2022rze: Changing-look AGN mimicking a supernova in a merging galaxy system
P. J. Pessi, R. Lunnan, J. Sollerman +36
AT2022rze is a luminous, ambiguous transient located South-East of the geometric center of its host galaxy at redshift z = 0.08. The host appears to be formed by a merging galaxy s…
EP 250108a/SN 2025kg: Observations of the most nearby Broad-Line Type Ic Supernova following an Einstein Probe Fast X-ray Transient
J. C. Rastinejad, A. J. Levan, P. G. Jonker +66
With a small sample of fast X-ray transients (FXTs) with multi-wavelength counterparts discovered to date, the progenitors of FXTs and their connections to gamma-ray bursts (GRBs)…
ZTF SN Ia DR2: High-velocity components in the Si II 6355
L. Harvey, K. Maguire, U. Burgaz +27
The ZTF SN Ia Data Release 2 provides a perfect opportunity to perform a thorough search for, and subsequent analysis of, high-velocity components in the Si II 6355 feature in t…
The Massive and Quiescent Elliptical Host Galaxy of the Repeating Fast Radio Burst FRB20240209A
T. Eftekhari, Y. Dong, W. Fong +39
The discovery and localization of FRB20240209A by the Canadian Hydrogen Intensity Mapping Fast Radio Burst (CHIME/FRB) experiment marks the first repeating FRB localized with the C…
ZTF SN Ia DR2: The diversity and relative rates of the thermonuclear SN population
G. Dimitriadis, U. Burgaz, M. Deckers +28
The Zwicky Transient Facility SN Ia Data Release 2 (ZTF SN Ia DR2) contains more than 3,000 Type Ia supernovae (SNe Ia), providing the largest homogeneous low-redshift sample of SN…
Euclid. III. The NISP Instrument
Euclid Collaboration, K. Jahnke, W. Gillard +434
The Near-Infrared Spectrometer and Photometer (NISP) on board the Euclid satellite provides multiband photometry and R>=450 slitless grism spectroscopy in the 950-2020nm wavelength…
Stellar halo density with LAMOST K and M giants
M. Lopez-Corredoira, X. -C. Tang, H. Tian +3
AIMS. We derive the morphology of the stellar component in the outer halo volume, and search for possible overdensities due to substructures therein. METHODS. We made use of some o…
