We analyzed seven, target ID 31686, Swift follow-up observations of the neutron-star X-ray transient Swfit J1749.4-2807 (Wijnands et al. 2009) currently in...

We have conducted an extensive observational campaign of SWIFT J1753.5-0127 over the last year, since its bright our-burst episode in 2005. Using long time...

Optical and near-IR observations were carried out with the 0.82mIAC80, 1.23m CAHA, 1.5m OSN and 3.5m CAHA telescopes as follows.

We report on optical spectroscopy of the high-energy transient Swift J1910.2-0546 / MAXI 1910-057 (ATel #4139; #4140; #4171; #4195; #4198) using the 2m...

Most of the transient sources that are detected in the gamma-ray sky are produced by extragalactic gamma-ray bursts (GRBs). However, it is known that there are...

We present the preliminary results of a year-long Swift monitoring campaign of the high-redshift (z=2.172) flat-spectrum radio quasar (FSRQ) S5 0836+710 (4C 71...

Swift has been monitoring the accreting millisecond pulsar IGR J17498-2921 since the start of its outburst in 2011 August 12 (ATels #3551, #3555, #3556). We...
