The ASAS-SN Bright Supernova Catalog I. 20132014
T. W. -S. Holoien, K. Z. Stanek, C. S. Kochanek +32
We present basic statistics for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) during its first year-and-a-half of operations, spanning 2013 and…
Massive stars exploding in a He-rich circumstellar medium - VII. The metamorphosis of ASASSN-15ed from a narrow line Type Ibn to a normal Type Ib Supernova
A. Pastorello, J. L. Prieto, N. Elias-Rosa +39
We present the results of the spectroscopic and photometric monitoring campaign of ASASSN-15ed. The transient was discovered quite young by the All Sky Automated Survey for SuperNo…
The Man Behind the Curtain: X-rays Drive the UV through NIR Variability in the 2013 AGN Outburst in NGC 2617
B. J. Shappee, J. L. Prieto, D. Grupe +44
After the All-Sky Automated Survey for SuperNovae (ASAS-SN) discovered a significant brightening of the inner region of NGC 2617, we began a ~70 day photometric and spectroscopic m…
ASASSN-15oi: A Rapidly Evolving, Luminous Tidal Disruption Event at 216 Mpc
T. W. -S. Holoien, C. S. Kochanek, J. L. Prieto +17
We present ground-based and Swift photometric and spectroscopic observations of the tidal disruption event (TDE) ASASSN-15oi, discovered at the center of 2MASX J20390918-3045201 ($…
Six Months of Multi-Wavelength Follow-up of the Tidal Disruption Candidate ASASSN-14li and Implied TDE Rates from ASAS-SN
T. W. -S. Holoien, C. S. Kochanek, J. L. Prieto +21
We present ground-based and Swift photometric and spectroscopic observations of the candidate tidal disruption event (TDE) ASASSN-14li, found at the center of PGC 043234 ($d\simeq9…
ASASSN-15lh: A Highly Super-Luminous Supernova
Subo Dong, B. J. Shappee, J. L. Prieto +27
We report the discovery of ASASSN-15lh (SN 2015L), which we interpret as the most luminous supernova yet found. At redshift z = 0.2326, ASASSN-15lh reached an absolute magnitude of…
The Young and Bright Type Ia Supernova ASASSN-14lp: Discovery, Early-Time Observations, First-Light Time, Distance to NGC 4666, and Progenitor Constraints
B. J. Shappee, A. L. Piro, T. W. -S. Holoien +29
On 2014 Dec. 9.61, the All-Sky Automated Survey for SuperNovae (ASAS-SN or "Assassin") discovered ASASSN-14lp just days after first light using a global array of 14-cm diam…
The ASAS-SN Bright Supernova Catalog II. 2015
T. W. -S. Holoien, J. S. Brown, K. Z. Stanek +41
This manuscript presents information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) during 2015, its second full year of operations. The sam…
ASASSN-14ae: A Tidal Disruption Event at 200 Mpc
Thomas W. -S. Holoien, J. L. Prieto, D. Bersier +12
ASASSN-14ae is a candidate tidal disruption event (TDE) found at the center of SDSS J110840.11+340552.2 (~Mpc) by the All-Sky Automated Survey for Supernovae (ASAS-SN).…
Discovery and Observations of ASASSN-13db, an EX Lupi-Type Accretion Event on a Low-Mass T Tauri Star
Thomas W. -S. Holoien, Jose L. Prieto, Krzysztof Z. Stanek +19
We discuss ASASSN-13db, an EX Lupi-type ("EXor") accretion event on the young stellar object (YSO) SDSS J051011.01032826.2 (hereafter SDSSJ0510) discovered by the All-Sky Automa…
Discovery and Observations of the Unusually Luminous Type-Defying II-P/II-L Supernova ASASSN-13co
T. W. -S. Holoien, J. L. Prieto, O. Pejcha +13
We present photometric and spectroscopic observations of ASASSN-13co, an unusually luminous Type II supernova and the first core-collapse supernova discovered by the All-Sky Automa…
Self-organised criticality in stochastic sandpiles: Connection to directed percolation
U. Basu, P. K. Mohanty
We introduce a stochastic sandpile model where finite drive and dissipation are coupled to the activity field. The absorbing phase transition here, as expected, belongs to the dire…
Characterizing a Dramatic Flare on an Ultracool Dwarf Found by the ASAS-SN Survey
Sarah J. Schmidt, Jose L. Prieto, K. Z. Stanek +19
We analyze a magnitude flare on the newly identified M8 dwarf SDSS J022116.84+194020.4 (hereafter SDSSJ0221) detected as part of the All-Sky Automated Survey for Supern…
Dynamics of a colloidal particle coupled to a Gaussian field: from a confinement-dependent to a non-linear memory
U. Basu, V. Démery, A. Gambassi
The effective dynamics of a colloidal particle immersed in a complex medium is often described in terms of an overdamped linear Langevin equation for its velocity with a memory ker…
