Aims : We study the impact of galaxy-galaxy interactions on the far-infrared properties of galaxies and its evolution at 0 < z < 1.2 .

Methods : Using the high- z galaxies in the fields of Great Observatories Origins Deep Survey ( GOODS ) observed by Herschel Space Observatory in the framework of the GOODS- Herschel key program and the local IRAS or AKARI-selected galaxies in the field of Sloan Digital Sky Survey Data Release 7 , we investigate the dependence of galaxy properties on the morphology of and the distance to the nearest neighbor galaxy .

Results : We find that the star formation rates ( SFRs ) and the specific SFRs ( SSFRs ) of galaxies , on average , depend on the morphology of and the distance to the nearest neighbor galaxy in this redshift range .
When a late-type galaxy has a close neighbor galaxy , the SFR and the SSFR increase as it approaches a late-type neighbor , which is supported by Kolmogorov-Smirnov ( K-S ) and Monte Carlo ( MC ) tests with a significance level of > 99 % .
However , the SFR and the SSFR decrease or do not change much as it approaches an early-type neighbor .
The bifurcations of SFRs and SSFRs depending on the neighbor ’ s morphology seem to occur at R _ { n } \approx 0.5 r _ { vir,nei } ( virial radius of the neighbor ) , which is supported by K-S and MC tests with a significance level of > 98 % .
For all redshift bins , the SSFRs of late-type galaxies interacting with late-type neighbors are increased by factors of about 1.8 \pm 0.7 and 4.0 \pm 1.2 compared to those of non-interacting galaxies when the pair separation is smaller than 0.5 r _ { vir,nei } and 0.1 r _ { vir,nei } , respectively .
The dust temperature of both local and high- z late-type galaxies strongly interacting with late-type neighbors ( i.e . R _ { n } \leq 0.1 r _ { vir,nei } ) appears to be higher than that of non-interacting galaxies with a significance level of 96 - 99 % .
However , the dust temperature of local late-type galaxies strongly interacting with early-type neighbors seems to be lower than or similar to that of non-interacting galaxies .

Conclusions : Our results suggest that galaxy-galaxy interactions and mergers have been strongly affecting the SFR and the dust properties of star-forming galaxies over at least 8 billion years .
