Abstract

The International Liquid Mirror Telescope (ILMT) is a 4-m optical ({\em gri} spectral bands) zenithal survey telescope with a field of view of 22.3$\times$22.3 arcmin, suitable for discovery and follow-up of faint transients. With the \texttt{PyLMT} pipeline, several new transients, including supernova candidates, are being discovered and detected routinely. We report the discovery of six supernova candidates, AT~2023yjc, AT~2024agkc, AT~2024aifv, AT~2024aiha, AT~2024fxn, and AT~2024zsm, using the ILMT. Ten additional supernova candidates were discovered in other surveys but were also detected with the ILMT. Here, we present the light curves of all supernova candidates observed with the ILMT in the {\em gri} bands. The basic light curve parameters, such as the rise time, decline rate, and peak magnitude, are estimated and reported.

Fast X-ray Transient EP260321a: Shock Breakout through an Extended Circumstellar Matter

The Einstein Probe (EP) has discovered a fast X-ray transient, EP260321a, whose optical counterpart was subsequently classified as a broad-lined Type Ic supernova. Its observed rise time of about 690 seconds is inconsistent with theoretical predictions for shock breakout (SBO) from a Wolf-Rayet star, which is typically regarded as the progenitor of envelope-stripped supernovae. In this paper, we propose that EP260321a arose from a SBO within extended circumstellar matter (CSM), where breakout photons were initially trapped, then diffused out of the unshocked CSM as the ejecta expanded and the opacity decreased. We modeled this photon diffusion process using both Monte Carlo simulations and an analytical approach to describe the temperature evolution. Through Markov Chain Monte Carlo sampling, we obtain the best-fit CSM parameters of log10(Mcsm/Msun) = -3.3 for the total CSM mass, Rin = 160 Rsun for the inner CSM radius, and Rout = 612 Rsun for the outer CSM radius. The presence of such a dense CSM indicates that the progenitor of EP260321a underwent episodic mass loss just days before the explosion, providing new observational constraints on the late-stage evolution of massive stars.

Detecting and Identifying Supernovae in AGN Accretion Disks

Stars may become embedded in active galactic nucleus (AGN) accretion disks and eventually explode as supernovae (SNe), whose detection would provide direct evidence for the existence and evolution of stars in AGN disks. We investigate the electromagnetic emission of such disk SNe using an analytic shock dynamics model coupled with a one-zone radiation model. Applying this framework to four progenitor types over a range of AGN black hole masses and Eddington ratios, we find that disk SNe around lower-mass black holes (BHs) or at lower Eddington ratios are more readily detectable against the underlying AGN emission and can remain detectable over a broader range of electromagnetic bands, from the infrared to soft X-rays. However, detectability against the AGN background does not guarantee that disk SNe can be distinguished from isolated SNe with CSM interaction. We therefore further compare disk SNe with isolated SNe with and without CSM interaction and find substantial degeneracies in their macroscopic observables. Nevertheless, we identify distinctive signatures that are robust across progenitor types. The characteristic emission shifts from the EUV for $M_{\rm BH}\lesssim10^7\,M_\odot$ toward the UV/optical for $M_{\rm BH}=10^8\,M_\odot$, with the visibility timescale increasing from less than a day to $\sim3\text{--}70$ days and $T_{\rm peak}\sim3\text{--}8$ eV in the latter case. The UV/optical regime around $10^8\,M_\odot$ BHs therefore offers particularly promising prospects for detecting disk SNe.

Neutrino production at the extreme vicinity of supermassive black hole in NGC 1068

The identification of NGC~1068 as an extragalactic high-energy neutrino source raises the question of the physical conditions required for neutrino production. Motivated by the newly updated IceCube data (down to $\sim 0.2 \,\rm TeV$) for NGC 1068, we present a statistical, model-independent inference primarily constrained by the multi-messenger observations. We calculate neutrino production from hadronic channels (including hadronuclear and photomeson processes) and the accompanying cascade gamma rays, and then employ the Latin hypercube sampling (LHS) method to explore the parameter space comprehensively, constrained by observational data. According to our results, the emission region is tightly limited: $R \gtrsim 10\,R_{\rm s}$ is excluded at $\sim 5σ$, and $R \gtrsim 6\,R_{\rm s}$ at $\sim 3σ$, where $R_{\rm s}$ is Schwarzschild radius of supermassive black hole (SMBH). Furthermore, reproducing $\gtrsim 80\%$ of the observed neutrino flux further restricts the emission to $R \lesssim 3R_{\rm s}$. Finally, we explore the possible particle acceleration mechanisms and find that stochastic acceleration naturally satisfies all constraints, whereas alternative mechanisms require extreme, fine-tuning parameters. We therefore identify stochastic acceleration as the most viable origin of the neutrino emission from NGC~1068.
