Expanding Horizons - Transforming Astronomy in the 2040s Time-Domain Multi-Messenger Astronomy in the 2040s: EM Follow-up of LGWA Sources
F. Patat, S. Piranomonte, S. Benetti +10
The coming decades will see gravitational-wave (GW) astronomy expand decisively into the mHz-Hz frequency range, opening access to a population of compact binaries that are current…
Spectropolarimetry of Type II supernovae (II) Intrinsic supernova polarization and its relations with the photometric/spectroscopic properties
T. Nagao, F. Patat, A. Cikota +6
The explosion processes of supernovae (SNe) are imprinted in their explosion geometries. Here, we study the intrinsic polarization of 15 hydrogen-rich core-collapse SNe and explore…
JWST Low-Resolution MIRI Spectral Observations of SN~2021aefx: High-density Burning in a Type Ia Supernova
J. M. DerKacy, C. Ashall, P. Hoeflich +38
We present a JWST/MIRI low-resolution mid-infrared (MIR) spectroscopic observation of the normal Type Ia supernova (SN Ia) SN 2021aefx at +323 days past rest-frame B-band maximum l…
Hidden shock powering the peak of SN 2020faa
I. Salmaso, E. Cappellaro, L. Tartaglia +9
The link between the fate of the most massive stars and the resulting supernova (SN) explosion is still a matter of debate, in major part because of the ambiguity among light-curve…
Polarimetry of Hydrogen-Poor Superluminous Supernovae
M. Pursiainen, G. Leloudas, A. Cikota +11
We present linear polarimetry for seven hydrogen-poor superluminous supernovae (SLSNe-I). For SN 2017gci, for which we present two epochs of spectropolarimetry at +3 d and +29 d po…
Reveals Spectacular Light Echoes Associated with the Stripped-envelope Supernova 2016adj in the Iconic Dust Lane of Centaurus A
Maximilian Stritzinger, Francesco Taddia, Stephen S. Lawrence +6
We present a multi-band sequence of images documenting the emergence and evolution of multiple light echoes (LEs) linked to the stripped-envelope supernova…
SN 2018bsz: a Type I superluminous supernova with aspherical circumstellar material
M. Pursiainen, G. Leloudas, E. Paraskeva +26
We present a spectroscopic analysis of Type I superluminous supernova (SLSN-I), SN 2018bsz. While it closely resembles SLSNe-I, the multi-component H line appearing at …
Evidence for multiple origins of fast declining Type II supernovae from spectropolarimetry of SN 2013ej and SN 2017ahn
T. Nagao, F. Patat, S. Taubenberger +10
The origin of the diverse light-curve shapes of Type II supernovae (SNe), and whether they come from similar or distinct progenitors, has been actively discussed for decades. Here…
Tips and Tricks in linear imaging polarimetry of extended sources with FORS2 at the VLT
S. González-Gaitán, A. M. Mourão, F. Patat +5
Context: Polarimetry is a very powerful tool to uncover various properties of astronomical objects that remain otherwise hidden in standard imaging or spectroscopic observations. H…
Continuum Foreground Polarization and Na~I Absorption in Type Ia SNe
P. Zelaya, A. Clocchiatti, D. Baade +9
We present a study of the continuum polarization over the 400--600 nm range of 19 Type Ia SNe obtained with FORS at the VLT. We separate them in those that show Na I D lines at the…
500 Days of SN 2013dy: spectra and photometry from the ultraviolet to the infrared
Y. -C. Pan, R. J. Foley, M. Kromer +23
SN 2013dy is a Type Ia supernova for which we have compiled an extraordinary dataset spanning from 0.1 to ~ 500 days after explosion. We present 10 epochs of ultraviolet (UV) throu…
VLT Spectropolarimetry of the fast expanding Type Ia SN2006X
F. Patat, D. Baade, P. Hoeflich +3
Using VLT-FORS1 we performed optical spectropolarimetric observations of the Type Ia SN2006X on 7 pre-maximum epochs (day -10 to day -1) and one post-maximum epoch (+39 days). The…
