Probing the origin of the extended flaring branch of Z-type X-ray binaries GX 340+0 and GX 5-1 using AstroSat
Tanmoy Dutta, Mayukh Pahari, Anish Sarkar +2
`Z' type neutron star low-mass X-ray binaries typically show a `Z'-like three-branched track in their hardness intensity diagram. However, a few such `Z' sources show an additional…
X-ray and Radio Campaign of the Z-source GX 340+0 II: the X-ray polarization in the normal branch
Yash Bhargava, Thomas D. Russell, Mason Ng +11
We present the first X-ray polarization measurement of the neutron star low-mass X-ray binary and Z-source, GX 3400, in the normal branch (NB) using a 200 ks observation with th…
Probing outbursts of the transient neutron star low mass X-ray binary Aql X-1 with NICER: a study of spectral evolution
Karthik Gananath Putha, Yash Bhargava, Sudip Bhattacharyya
X-ray observations of neutron star (NS) low mass X-ray binaries (LMXBs) are useful to probe physical processes close to the NS and to constrain source parameters. Aql X-1 is a tran…
Rapid Mid-Infrared Spectral-Timing with JWST. I. The prototypical black hole X-ray Binary GRS 1915+105 during a MIR-bright and X-ray-obscured state
P. Gandhi, E. S. Borowski, J. Byrom +44
We present mid-infrared (MIR) spectral-timing measurements of the prototypical Galactic microquasar GRS 1915+105. The source was observed with the Mid-Infrared Instrument (MIRI) on…
An IXPE-Led X-ray Spectro-Polarimetric Campaign on the Soft State of Cygnus X-1: X-ray Polarimetric Evidence for Strong Gravitational Lensing
James F. Steiner, Edward Nathan, Kun Hu +134
We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May-June. Companion multiwav…
X-ray and Radio campaign of the Z-source GX 340+0: discovery of X-ray polarization and its implications
Yash Bhargava, Mason Ng, Liang Zhang +11
We present the discovery of X-ray polarization from the neutron star low-mass X-ray binary and Z-source, GX~3400, using an Imaging X-ray Polarimetry Explorer (IXPE) observation…
AstroSat and NICER timing view of the Z-type Neutron Star X-ray binary GX 340+0
Mayukh Pahari, Shree Suman, Yash Bhargava +5
The timing properties of the Z-type low-mass X-ray binaries provide insights into the emission components involved in producing the unique Z-shaped track in the hardness-intensity…
