We present ground-based optical and Hubble Space Telescope (HST) optical and near-IR observations of the short-hard GRB 130603B at z = 0.356, which demonstrate the presence of excess near-IR emission matching the expected brightness and color of an r-process powered transient (a “kilonova”). The early afterglow fades rapidly with α ≲ −2.6 at t ≈ 8–32 hr post-burst and has a spectral index of β ≈ −1.5 (Fν∝tανβ), leading to an expected near-IR brightness at the time of the first HST observation… 

A kilonova associated with GRB 070809

For on-axis typical short gamma-ray bursts (sGRBs), the forward shock emission is usually so bright 1 , 2 that it renders the identification of kilonovae (also known as macronovae) 3 – 6 in the early

THE LIGHT CURVE OF THE MACRONOVA ASSOCIATED WITH THE LONG–SHORT BURST GRB 060614

The Swift-detected GRB 060614 was a unique burst that straddles an imaginary divide between long- and short-duration gamma-ray bursts (GRBs), and its physical origin has been heavily debated over the

A kilonova from an ultra-quick merger of a neutron star binary

GRB 060505 was the first well-known nearby (at redshift 0.089) “hybrid” gamma-ray burst that has a duration longer than 2 seconds but without the association of a supernova down to very stringent

A macronova associated with GRB 070809

GRB 070809 is a typical short gamma-ray burst (sGRB) detected by the Neil Gehrels {\it Swift} Observatory and at the location of the burst no underlying galaxy down to $\sim 28$th AB magnitude in

We present the discovery of the radio afterglow and near-infrared (NIR) counterpart of the Swift short gamma-ray burst (GRB) GRB 200522A, located at a small projected offset of ≈1 kpc from the center

IS THE LATE NEAR-INFRARED BUMP IN SHORT-HARD GRB 130603B DUE TO THE LI-PACZYNSKI KILONOVA?

Short–hard gamma-ray bursts (GRBs) are widely believed to be produced by the merger of two binary compact objects, specifically by two neutron stars or by a neutron star orbiting a black hole.

Infrared Emission from Kilonovae: The Case of the Nearby Short Hard Burst GRB 160821B

We present constraints on Ks-band emission from one of the nearest short hard gamma-ray bursts, GRB 160821B, at z = 0.16, at three epochs. We detect a red relativistic afterglow from the jetted

The Macronova in GRB 050709 and the GRB-macronova connection

A reanalysis of the publicly available data of this event and the discovery of a Li-Paczynski macronova/kilonova that dominates the optical/infrared signal at t>2.5 days supports the suggestion that compact binary mergers are significant and possibly main sites of heavy r-process nucleosynthesis.

A luminosity distribution for kilonovae based on short gamma-ray burst afterglows

The combined detection of a gravitational-wave signal, kilonova, and short gamma-ray burst (sGRB) from GW170817 marked a scientific breakthrough in the field of multimessenger astronomy. But even

The optical afterglow of the short γ-ray burst GRB 050709

It has long been known that there are two classes of γ-ray bursts (GRBs), mainly distinguished by their durations. The breakthrough in our understanding of long-duration GRBs (those lasting more than

A short γ-ray burst apparently associated with an elliptical galaxy at redshift z = 0.225

Gamma-ray bursts (GRBs) come in two classes: long (> 2 s), soft-spectrum bursts and short, hard events. Most progress has been made on understanding the long GRBs, which are typically observed at

A ‘kilonova’ associated with the short-duration γ-ray burst GRB 130603B

Optical and near-infrared observations provide strong evidence that compact-object mergers are the progenitors of short-duration γ-ray bursts and the sites of significant production of r-process elements, and suggest that kilonovae offer an alternative, unbeamed electromagnetic signature of the most promising sources for direct detection of gravitational waves.
