I report detections of four new H i 21-cm absorbers associated with sources at intermediate redshifts , 0.7 < z < 1.0 .
The sources are part of a sample of 11 radio-loud galaxies , all at 0.7 < z < 1.0 , that were searched for associated H i 21-cm absorption using uGMRT .
Previously , just four such absorbers were known in the literature at these redshifts ; the current observations have increased the total to eight .
The results indicate that the detection fraction at intermediate redshifts could be as high as that at lower redshifts , \approx 30 \% , on contrary to a much lower detection fraction observed in samples at z > 1 .
Three detections show strong blueshifted features , indicating cold gas outflows .
These three sources also tentatively show excess [ O ii ] line luminosity compared to a bulk of the remaining sample , possibly suggesting that the hosts of these AGNs harbour different environments , either due to interaction with the radio jets or due to excess star formation in the host galaxy .
Further , a cold H i mass outflow rate of \approx 78 M _ { \odot } yr ^ { -1 } , assuming { T _ { s } = 1000 } K , is estimated for the detection towards SDSS J014652.79-015721.2 , at z = 0.95904 , which is the highest till date in comparison to similar estimates available in the literature .
