GFH-v2 Pipeline for Searches of Long-Transient Gravitational Waves from Newborn Magnetars
Sandhya Sajith Menon, Lorenzo Pierini, Pia Astone +11
This paper presents an enhanced methodology for searching long transient gravitational waves associated with a newborn magnetar, with particular focus on the regime in which the ea…
A Deep Precursor-Dip-Main Superoutburst Sequence in VW Hydri Observed with TESS: High-Cadence Constraints on the Thermal-Tidal Instability Model
Bisi Bernard Ogunwale, Shara Michael, Avi Shporer +2
We present 120s cadence TESS observations of three superoutbursts of the SU UMa-type dwarf nova VW Hydri. Two events (SO2 in Sectors 87+88 and SO3 in Sector 93) exhibit a pronounce…
The TEQUILA catalog of variables in TESS full-frame images: Differential photometry light curves from the first two years of observations
Bisi Bernard Ogunwale, Yossi Zaguri, Volker Perdelwitz +4
Stellar variability and transient events provide critical insights into astrophysics, accelerated by missions like CoRoT, Kepler, and K2. NASA's Transiting Exoplanet Survey Satelli…
An optical--mid-infrared color evolution tool for nova identification using WISE data
Joseph Onuegbu, Dafne Guetta, Yael Hillman +2
We present a novel approach for characterizing nova candidates by exploiting the infrared capabilities of the Wide-field Infrared Survey Explorer (WISE) catalog. We developed a pip…
Ultraviolet radiation and neutrinos: two messengers from CCSNe in the CSM scenario
Silvia Gagliardini, Simone Dall'Osso, Dafne Guetta +4
Massive stars (>8 ) often undergo intense mass loss through winds or eruptive events in the final stages of their evolution, leading to the formation of a dense circumst…
Prospects for Time-Domain and Multi-Messenger Science with eXTP
Shu-Xu Yi, Wen Zhao, Ren-Xin Xu +75
In this new era of time-domain and multi-messenger astronomy, various new transients and new phenomena are constantly being discovered thanks to the rapid advances in observations,…
