A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294
Shifra Mandel, Kaya Mori, Paul A. Draghis +37
For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…
A low mass, binary-stripped envelope for the Type IIb SN 2024abfo
S. de Wet, G. Leloudas, D. Buckley +3
Type IIb supernovae (SNe) are a transitional subclass of stripped-envelope SNe showing hydrogen lines in their spectra that gradually weaken and give way to helium lines reminiscen…
Efficient Bayesian analysis of kilonovae and gamma ray burst afterglows with fiesta
Hauke Koehn, Thibeau Wouters, Peter T. H. Pang +4
Gamma-ray burst (GRB) afterglows and kilonovae (KNe) are electromagnetic transients that can accompany binary neutron star (BNS) mergers. Therefore, studying their emission process…
Detection of low-luminosity X-ray pulsations from the accreting millisecond pulsar IGR J17511-3057: An ever-thinning thread between bright accretion and sub-luminous states
Giulia Illiano, Alessandro Papitto, Sergio Campana +14
After nearly a decade in quiescence, the accreting millisecond pulsar IGR J175113057 displayed a new outburst on 2025 February 11, its third since discovery, following previous…

M. Pursiainen, G. Leloudas, J. Lyman +14
We present an analysis of twenty tidal disruption event (TDE) host galaxies observed with the MUSE integral-field spectrograph on ESO VLT. We investigate the presence of extended e…
Dense Matter in Neutron Stars with eXTP
Ang Li, Anna L. Watts, Guobao Zhang +82
In this White Paper, we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission to constrain the equation of state of dense matter in neutron stars, explo…
SN 2024bfu, SN 2025qe, and the early light curves of type Iax supernovae
M. R. Magee, T. L. Killestein, M. Pursiainen +39
Type Iax supernovae (SNe Iax) are one of the most common subclasses of thermonuclear supernova and yet their sample size, particularly those observed shortly after explosion, remai…
